|Problem:||Cheryl took 7 math tests in one marking period. What is the range of her test scores?|
|89, 73, 84, 91, 87, 77, 94|
|Solution:||Ordering the test scores from least to greatest, we get:|
|73, 77, 84, 87, 89, 91, 94|
|highest - lowest = 94 - 73 = 21|
|Answer:||The range of these test scores is 21 points.|
|Definition:||The range of a set of data is the difference between the highest and lowest values in the set.|
In the problem above, the set of data consists of 7 test scores. We ordered the data from least to greatest before finding the range. We recommend that you do this, too. This is especially important with large sets of data.

Here are some notes on setting for your reference:
SETTING -- The time and location in which a story takes place is called the setting. For some stories the setting is very important, while for others it is not. There are several aspects of a story's setting to consider when examining how setting contributes to a story (some, or all, may be present in a story):
a) place - geographical location. Where is the action of the story taking place?
b) time - When is the story taking place? (historical period, time of day, year, etc)
c) weather conditions - Is it rainy, sunny, stormy, etc?
d) social conditions - What is the daily life of the character's like? Does the story contain local colour (writing that focuses on the speech, dress, mannerisms, customs, etc. of a particular place)?
e) mood or atmosphere - What feeling is created at the beginning of the story? Is it bright and cheerful or dark and frightening?
Keeping in mind of the setting of a story is important to our understanding of the story. If we know how the setting affects the mood of the story, we gain a better understanding of how the characters in the story are feeling.

Experimental probability of an event is the ratio of the number of times the event occurs to the total number of trials.
Examples of Experimental Probability
Sam rolled a number cube 50 times. A 3 appeared 10 times.
Then the experimental probability of rolling a 3 is 10 out of 50 or 20%.
Solved Example on Experimental Probability
A coin is tossed 60 times. 27 times head appeared. Find the experimental probability of getting heads.
Correct Answer: B
Step 1: Experimental probability = number of times the event occurs / total number of trials.
Step 2: Number of times heads appeared = 27.
Step 3: Total number of experiments = 60.
Step 4: So, experimental probability of getting a head = 27/60. Then, you simplify and you get: 9/20.

Exposition: the start of the story, the situation before the action starts
Rising Action: the series of conflicts and crisis in the story that lead to the climax
Climax: the turning point, the most intense moment—either mentally or in action
Falling Action: all of the action which follows the climax
Resolution: the conclusion, the tying together of all of the threads
Character vs Character:
This type of conflict finds the main character in conflict with another character, human or not human.
Character vs Nature:
This type of conflict finds the main character in conflict with the forces of nature, which serve as the antagonist.
Character vs Society:
This type of conflict has the main character in conflict with a larger group: a community, society, culture, etc.
Character vs Self:
In this type of conflict, the main character experiences some kind of inner conflict.
They are almost always round or three-dimensional characters. They have good and bad qualities. Their goals, ambitions, and values change. A round character changes as a result of what happens to him or her.
A character who changes inside as a result of what happens to him is referred to in literature as a DYNAMIC character. A dynamic character grows or progresses to a higher level of understanding in the course of the story.
Protagonist: The main character in the story
Antagonist: The character or force that opposes the protagonist.
Foil: A character who provides a contrast to the protagonist.
They are almost always flat or two-dimensional characters. They have only one or two striking qualities. Their predominant quality is not balanced by an opposite quality. They are usually all good or all bad. Such characters can be interesting or amusing in their own right, but they lack depth. Flat characters are sometimes referred to as STATIC characters because they do not change in the course of the story.
POINT OF VIEW: The identity of the narrative voice; the person or entity through whom the reader experiences the story. May be third-person (no narrator; abstract narrative voice, omniscient or limited) or first-person (narrated by a character in the story or a direct observer). Point-of-view is a commonly misused term; it does not refer to the author’s or characters’ feelings, opinions, perspectives, biases, etc.
THESE ARE POINTS OF VIEW:
The narrator is a character in the story who can reveal only personal thoughts and feelings and what he or she sees and is told by other characters. He can’t tell us thoughts of other characters.
The narrator is an outsider who can report only what he or she sees and hears. This narrator can tell us what is happening, but he can’t tell us the thoughts of the characters.
The narrator is an outsider who sees into the mind of one of the characters.
The narrator is an all-knowing outsider who can enter the minds of more than one of the characters.
Study for your WWW quiz
On your quiz, you will have to know the meaning of your words and how to spell them correctly.

| There are 3 red candies left in a bag of multicolored candies with a total of 20 candies left in it. The probability that you will get a red one when you reach in is: 3/20. |
But what are your chances of getting a red one if you reach in again?
There are now 19 candies in the bag, and only two are red.
The probability is 2/19.
Taking the first candy affected the outcome of the next attempt.
The two events are dependent.
| Now you know that the probability of heads landing up when you flip a coin is 1/2. |
What is the probability of getting tails if you flip it again?
It is still 1/2.
The two events do not affect each other. They are independent.

1. When the subject of a sentence is composed of two or more nouns or pronouns connected by and, use a plural verb.
She and her friends are at the fair.
2. When two or more singular nouns or pronouns are connected by or or nor, use a singular verb.
The book or the pen is in the drawer.
3. When a compound subject contains both a singular and a plural noun or pronoun joined by or or nor, the verb should agree with the part of the subject that is nearer the verb.
The boy or his friends run every day.
His friends or the boy runs every day.
4. Doesn't is a contraction of does not and should be used only with a singular subject. Don't is a contraction of do not and should be used only with a plural subject.
The exception to this rule appears in the case of the first person and second person pronouns I and you. With these pronouns, the contraction don't should be used.
He doesn't like it.
They don't like it.
5. Do not be misled by a phrase that comes between the subject and the verb. The verb agrees with the subject, not with a noun or pronoun in the phrase.
One of the boxes is open.
The people who listen to that music are few.
The team captain, as well as his players, is anxious.
The book, including all the chapters in the first section, is boring.
The woman with all the dogs walks down my street.
6. The words each, each one, either, neither, everyone, everybody, anybody, anyone, nobody, somebody, someone, and no one are singular and require a singular verb.
Each of these hot dogs is juicy.
Everybody knows Mr. Jones.
Either is correct.
7. Nouns such as civics, mathematics, dollars, measles, and news require singular verbs.
The news is on at six.
Note: the word dollars is a special case. When talking about an amount of money, it requires a singular verb, but when referring to the dollars themselves, a plural verb is required.
Five dollars is a lot of money.
Dollars are often used instead of rubles in Russia.
8. Nouns such as scissors, tweezers, trousers, and shears require plural verbs. (There are two parts to these things.)
These scissors are dull.
Those trousers are made of wool.
9. In sentences beginning with there is or there are, the subject follows the verb. Since there is not the subject, the verb agrees with what follows.
There are many questions.
There is a question.
10. Collective nouns are words that imply more than one person but that are considered singular and take a singular verb, such as: group, team, committee, class, and family.
In very few cases, the plural verb is used if the individuals in the group are thought of and specifically referred to.
The team runs during practice.
The committee decides how to proceed.
The family has a long history.
My family have never been able to agree.
11. Expressions such as with, together with, including, accompanied by, in addition to, or as well do not change the number of the subject. If the subject is singular, the verb is too.
The President, accompanied by his wife, is traveling to India.
All of the books, including yours, are in that box.

An inequality is used when we don't know exactly what an expression is equal to.
In order to solve an inequality, we have to combine like terms like you would if you were solving an equation.
For example, if you are asked to solve for x in the following equation: 5x + 3 = 13, you all know that you had to subtract 3 from both sides of the equation because our goal is to get x by itself and also because we know we have to do the inverse operation. In this case, the inverse of addition is subtraction.
After you subtracted 3 from both sides of the equation, you should have been left with 5x = 10. We have to get 5 from x because again, our goal is to get x by itself. Because we know that 5x is really 5 times x, we know that we have to do the inverse of multiplication to get x alone. So, we divide both sides by 5. Then, we are left with x = 10.
We use the same skills we use to solve equations to solve inequalities. We have to remember that our goal is to end up with a variable on one side of the inequality and a value on the other side.
Abruptly: (adverb) sudden or unexpected
Delinquent: (noun) a person who is guilty of a misdeed or offense; someone who breaks the law
Appeal: (verb) to be especially attractive, pleasing, interesting, or enjoyable. If something appeals to you, it is pleasing to you. For example, the author appeals to my senses because he writes with such descriptive language.
Appeal is a word we have seen before, but it seems that many of you have forgotten it.

A Better Chance is the preeminent resource for identifying, recruiting and developing leaders among young people of color in the United States.
Through a unique assessment model, A Better Chance refers academically talented students entering grades 6 through 11 to some of the nation's finest independent and public schools to be considered for placement and financial aid. Students who are successfully placed in one of our 300+ member schools become a part of the signature College Preparatory Schools Program, and receive access to expanded educational and leadership opportunities.
The College Preparatory Schools Program (CPSP) is an academic program that identifies, recruits, places, and supports students of color, in outstanding college preparatory middle and high schools nationally.
At A Better, Chance we recognize that students come from different backgrounds and educational opportunities so each application is evaluated on its own merit. Generally, we select students who:
1) Consistently perform at or above grade level in math and English
2) Have an overall academic average of a B+ or better
3) Are ranked in the top 10 percent of the class
Students are required to take standardized tests. There are no score cut-offs but test scores are used to assess academic strength along with school transcripts, extracurricular activities and personal qualities. Selected applications are sent to our member schools, but it is the admission committees of each member school that make the final admission decisions.
Prospective applicants should get started early; late applications are not encouraged as it severly limits opportunities for placements. Further, our application process begins one year prior to enrolling. For example, if a student is currently in the 8th grade, s/he would be applying for the 9th grade.

Those of you who owe me ELA work have to do a 2-page essay for each assignment you missed. That is, if you owe me 10 assignments, then, you must do 10 2-page essays for me. I will be looking at content and grammar. If you put no care of effort into your work, I will be able to see that and will grade accordingly.
You could write about any topic. Some things that you could write about are:
What do you think of 7th grade so far?
What do you like doing on the weekends?
What do you like about our class book, The Outsiders? Why?
Do you feel that you have a voice in society? Why or why not?
What about your neighborhood bothers you? Why?
What makes you proud to be who you are? Why?
What makes you proud to be in the Power Point Class? Why?
What do you want in a teacher? Why?
If you could change anything about your school, what would you change? Why?
If your heart is telling you that you want to write a 20-page story instead of 10 2-page essays, that is fine too. I will not be lenient when grading these, as you should have done your work in the first place.
I am allowing you all to make up work, despite your irresponsibility, because I want you all to go to the high schools of your dreams. Next marking period, I will not allow you to make up any work. You have to learn to be on point and to be responsible. You all are mature and old enough by now.

The word rational refers to something reasonable, understandable, within reason. In short rational numbers are whole numbers, fractions, and decimals - the numbers we CAN understand and that we use in our daily lives.
In mathematical terms a number is rational if you can write it in a form a/b where a and b are integers, b not zero. Clearly all fractions are of that form. Terminating decimal numbers can easily be written in that form: for example 0.67 is 67/100, 3.40938 = 340938/100000 etc.
Terminates means to end. So, if you decimal ends, it is a rational number. For example, .46 is a rational number because it is terminating.
Rational numbers are contrasted with irrational numbers - such like Pi and square roots of non-perfect squares of numbers. In a sense you can't really understand the irrational numbers, because the name irrational itself means NOT rational, NOT reasonable, NOT understandable, NOT within reasoning powers.
A repeating decimal, also called a recurring decimal, is a number whose decimal representation eventually becomes periodic (i.e., the same sequence of digits repeats indefinitely).
.333333333333... is a repeating decimal because 3 repeats. The (...) tells you that 3 goes on and on and that the decimal is non-terminating, which I will go over shortly. (Look below)
Non-repeating decimals are decimals that do not have a repeating pattern. For example, the value for Pi is a non-repeating decimal. Its value is: 3.14159265.... You cannot predict any type of pattern for pi. It's irrational.
Terminating decimals are decimals are decimals that END; they do not go on and on and on and on. 6.5 and 0.0000034 are examples of terminating decimals. They stop. They do not go on and on.
Non-terminating decimals do not end. They go on forever. The (...) or the line over your decimals indicated that your decimals are non-terminating.
For example, 6.33333333333.... is non-terminating.
Now, how do we figure out what decimals are rational or irrational?
Irrational decimals will be BOTH non-terminating and non-repeating decimals. All other types of decimals will be rational. That is, if your decimal is not BOTH non-terminating and non-repeating, then, it is not irrational.
For example, if a number is non-terminating, but it is repeating, then it is rational. .3333... is repeating and non-terminating. It is rational because it does not BOTH non-repeating and non-terminating. It satisfies ONLY one of the rules.

Evade: verb: to avoid or escape by speed, cleverness, trickery

A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers.
- The number 8 is a rational number because it can be written as the fraction 8/1.
- Likewise, 3/4 is a rational number because it can be written as a fraction.
- Even a big, clunky fraction like 7,324,908/56,003,492 is rational, simply because it can be written as a fraction.
Every whole number is a rational number, because any whole number can be written as a fraction. For example, 4 can be written as 4/1, 65 can be written as 65/1, and 3,867 can be written as 3,867/1.
All numbers that are not rational are considered irrational. An irrational number can be written as a decimal, but not as a fraction.
An irrational number has endless non-repeating digits to the right of the decimal point. Here are some irrational numbers:
π = 3.141592…
Although irrational numbers are not often used in daily life, they do exist on the number line. In fact, between 0 and 1 on the number line, there are an infinite number of irrational numbers!
For more information besides the many handouts I gave you in class, this site is very helpful. Click here.
Briefly, the noun is a person, place, thing, or idea.
The adjective describes a noun.
The adverb indicates manner, time, place, cause, or degree and answers questions such as "how," "when," "where," "how much". Adverbs generally end in "ly."
The preposition usually indicates the temporal, spatial or logical relationship of its object to the rest of the sentence.
The interjection is a word added to a sentence to convey emotion. It is not grammatically related to any other part of the sentence.
You can use a conjunction to link words, phrases, and clauses, as in the following example:
- I ate the pizza and the pasta.
- Call the movers when you are ready.
he verb is perhaps the most important part of the sentence.
A verb or compound verb asserts something about the subject of the sentence and express actions, events, or states of being.

Apprehensive (adjective): uneasy or fearful about something that might happen.
Aloofness (noun): at a distance, esp. in feeling or interest; apart.
Defiance (noun): a daring or bold resistance to authority or to any opposing force.
Contemptuously (adverb): showing or expressing contempt or disdain; scornful.
Scientists have developed a shorter method to express very large numbers. This method is called scientific notation. Scientific Notation is based on powers of the base number 10.
The notation is based on powers of base number 10. The general format looks something like this:
N X 10x where N= number greater than or equal to 1 but less than 10 and x=exponent of base 10.
Placing numbers in exponential notation has several advantages.
For very large numbers and extrememly small ones, these numbers can be placed in scientific notation in order to express them in a more concise form.
In addition, numbers placed in this notation can be used in a computation with far greater ease. This last advantage was more practical before the advent of calculators and their abundance.
In scientific fields, scientific notation is still used.
Let's first discuss how we will express a number greater than 10 in such notational form.
Numbers Greater Than 10
We first want to locate the decimal and move it either right or left so that there are only one non-zero digit to its left.
The resulting placement of the decimal will produce the N part of the standard scientific notational expression.
Count the number of places that you had to move the decimal, and that would be your x, exponent.
If it is to the left as it will be for numbers greater than 10, that number of positions will equal x, the exponent, in the general expression above.
As an example, how do we place the number 2340000 in standard scientific notation?
Position the decimal so that there is only one non-zero digit to its left. In this case we end up with 2.34. We know that 2.34 has to be less than 10 and has to be greater than or equal to 1.
Count the number of positions we had to move the decimal to the left and that will be the exponent, x.
So we have: 2.34 X 106 in scientific notation.
That is how we convert from standard form to scientific notation.
Now, how do we go from scientific notation to standard form:
(1) Move decimal point to right the same amount of times your exponent tells you to.
For example, if your base ten exponential has an exponent of 5, you have to move the decimal point to the right 5 times.
That is, 5.67 x 105 is: 567000.
Good luck!! You all did a great job in class today.

Remember: When multiplying exponentials, there are two laws that can help you simplify the expression.
1st Multiplication Law: If the exponentials have the same base, add the powers.
2nd Multiplication Law: If the exponentials have the same power, multiply the bases.
Use the above laws to simplify the following problems.
1. 123 × 23 = ____________
2. 46 × 36 = ____________
3. 55 × 53 = ____________
4. 254 × 44 = ____________
5. 39 × 339 = ____________
6. 1012 × 104 = ____________
7. 75 × 35 = ____________
8. 246 × 36 = ____________
Problem number 3 follows the 1st law for multiplication of exponentials (bases are the same). Write a problem that follows the 2nd law for multiplication of exponentials and simplify it.
Base: The number used as a factor for repeated multiplication (the big number on the bottom)
Power: The number of times the factor is being multiplied, a.k.a. exponent (the number up top)
Simplify: The change to a more simple form (not the same as evaluate or solve!!)
There are laws for simplifying the *multiplication* of exponentials:
1st Multiplication Law: If the exponentials have the same base, the powers can be added: 52 × 53 = 52+3 = 55.
It will be very important for students to see this in proof form, to help them visualize it: 52 × 53 = (5 × 5) × (5 × 5 × 5) = 5 × 5 × 5 × 5 × 5
2nd Multiplication Law: If the exponentials have the same powers, multiply the bases and keep the power: 53 × 63 = (5 × 6)3 = 303

What’s up with test corrections?
For every test that you take in this class, you are required to do test corrections even if you are satisfied with your grade. The point of test corrections is to give you the opportunity to improve and to demonstrate your understanding of the material.
When are test corrections due?
Test corrections are due a week after your receive your test. That is, if I give you back your test on Tuesday, you must return your test corrections to me by the following Tuesday. Since a week is sufficient time to work on your test correction, any late test corrections will result in a zero.
How to do a good test correction?
1. DO A TEST REFLECTION
On a separate piece of loose-leaf paper (not in your notebook), answer the following questions in complete sentences (so I can understand what you are trying to tell me!).
1. What grade did you get on your test?
2. What grade do you think you deserve (based on how much you learned from this unit)?
3. How much studying did you do for this test? Please describe HOW you prepared for this test.
4. Do you think your studying was effective? Why or why not?
5. Do you think you really UNDERSTAND this material?
2. CORRECT THE QUESTIONS YOU MISSED ON THE TEST ON A SEPARATE PIECE OF PAPER FROM YOUR REFLECTIONS
For EVERY SINGLE QUESTION you missed or lost ANY points on, do ALL of the following:
a. Write out the complete correct answer. (If you missed a multiple-choice question, you must write out an entire complete sentence, not just the letter of the answer. This does NOT mean you have to write out the entire question, just put the question into a complete sentence). You also must SHOW YOUR WORK.
b. You must explain how you came up with the correct answer.
b. Where did you find the correct answer? (This could be your notebook, the textbook, your brilliant teacher, etc)
3. ANSWER THIS LAST QUESTION
6. What (if anything) will you do differently next time while preparing for a test in this class?
4. STAPLE ALL THE PAGES TOGETHER, ATTACH YOUR TEST TO THE BACK, AND TURN THE WHOLE THING IN ON TIME!!!
How much are test corrections worth?
Test corrections are worth a quiz grade. If you do not complete your test corrections, you will get a zero. If your test corrections are late, you will receive a zero. If you received a perfect score on your initial test, then, you get an automatic 100 on the test correction!
Because of the rapid dismissal, I was unable to give you the homework that I had planned for you. Don't worry. I know how excited you all are for homework. Thus, I will make sure to give you lots of homework when you get back. :)
Enjoy your day off. See you Tuesday.

How to Square A Number
To square a number, just multiply it by itself ...
Example: What is 3 squared?
|3 Squared||=||=||3 × 3||=||9|
Note: we write down "3 Squared" as 32
(the little "2" means the number appears twice in multiplying)
Some More Squares
|4 Squared||=||42||=||4 × 4||=||16|
|5 Squared||=||52||=||5 × 5||=||25|
|6 Squared||=||62||=||6 × 6||=||36|
A square root goes the other direction:
3 squared is 9, so the square root of 9 is 3
The square root of a number is ...
... that special value that when multiplied by itself gives the original number.
The square root of 9 is ...
... 3, because when 3 is multiplied by itself you get 9.
Note: When you see "root" think
"I know the tree, but what is the root that produced it?"
In this case the tree is "9", and the root is "3".
Here are some more squares and square roots:
Example: What is the square root of 25?
Well, we just happen to know that 25 = 5 × 5, so if you multiply 5 by itself (5 × 5) you will get 25.
So the answer is 5
The Square Root Symbol
|This is the special symbol that means "square root", it is sort of like a tick, and actually started hundreds of years ago as a dot with a flick upwards. |
It is called the radical, and always makes math look important!
You can use it like this: (you would say "the square root of 9 equals 3")
More Advanced Topics Follow
You Can Also Square Negative Numbers
Have a look at this:
|If you square 5 you get 25:||5 × 5 = 25|
|But you could also square -5 to get 25:||-5 × -5 = 25|
|(because a negative times a negative gives a positive)|
So the square root of 25 can be 5 or -5
There can be a positive or negative answer to a square root!
But when people talk about "the" square root they usually mean just the positive one.
And when you use the radical symbol √ it always means just the positive one.
Example: √36 = 6 (not -6)
The perfect squares are the squares of the whole numbers:
It is easy to work out the square root of a perfect square, but it is really hard to work out other square roots.
Example: what is the square root of 10?
Well, 3 × 3 = 9 and 4 × 4 = 16, so we can guess the answer is between 3 and 4.
- Let's try 3.5: 3.5 × 3.5 = 12.25
- Let's try 3.2: 3.2 × 3.2 = 10.24
- Let's try 3.1: 3.1 × 3.1 = 9.61
Very slow ... at this point, I get out my calculator and it says:
... but the digits just go on and on, without any pattern. So even the calculator's answer is only an approximation !
(Further reading: these kind of numbers are called surds which are a special type of irrational number)
A Special Method for Calculating a Square Root
There are many ways to calculate a square root, but my favorite method is an easy one which gets more and more accurate depending on how many times you use it:
a) start with a guess (let's guess 4 is the square root of 10)
b) divide by the guess (10/4 = 2.5)
c) add that to the guess (2.5+4=6.5)
d) then divide that result by 2, in other words halve it. (6.5/2 = 3.25)
e) now, set that as the new guess, and start at b) again
... so, our first attempt got us from 4 to 3.25
Going again (b to e) gets us: 3.163
Going again (b to e) gets us: 3.1623
And so, after 3 times around the answer is 3.1623, which is pretty good, because:
3.1623 x 3.1623 = 10.00014This is fun to try - why not use it to try calculating the square root of 2?

These are a few of the possible answers for number 1. We know that an integer is a counting number that is a whole number. So, in order to answer this question, you need to know what an integer is and you have to know what a sum means. The sum is the answer you get when you add numbers together.
2) It is possible that -5 is larger than -10 even though the absolute value of -10 is larger than that of -5 because -5 is closer to zero and closer to positive numbers of the number line.

Mapping is how we lay out the ideas visually to find connections and to branch out and make new ideas and connections. Eventually mapping will lead you to a list of ideas and a sequence to use them in.
1. How to use mapping to generate ideas:
Write the topic in the middle of the page. Draw branches out from that topic and write keywords or phrases that you associate with that topic. Draw more branches out from each of those keywords (sub-topics) to develop each of those ideas. Look, then, at which of the sub-topics go together and if any of the extended ideas can link to each other. Draw branches and lines between the ideas that could work together. Decide, then, if you would like to regroup your ideas.
Write the topic in the middle of the page again and go through the first steps again with the new groupings.
Do this as many times as you like until you have clear responses and ideas that you can now form into the parts of an essay. With the bubbles and branches you can see how the ideas work, how they interrelate and how they work together as a whole.
Before you write your paper it is a good idea to choose what order your ideas will be written in. This will ensure that you answer the whole question, remember all the parts, and that your answer can have a logical flow. An essay is a complicated answer and it is important that all of the parts of the essay (introduction/body paragraphs/conclusion) work together in a way that is easy to read, logical, and that builds together to the conclusion. This can't happen if the parts are jumbled or random.
It is important to work out which idea should go first, which ideas are prerequisite to other ideas, etc. What is your most dramatic idea? Which ideas work together to form another, bigger idea? With all of these elements going on, it is important to write down a list of the order you will use. To decide on that order you may have to work out what kind of structure you need first or, if you already know that, you may be able to proceed straight to the plan (also known as an outline.)
Proportional reasoning involves the ability to compare and produce equal ratios. A common use of proportions occurs when making or using maps and scale models.
There are several ways to solve a proportion. One is related to how you find equivalent fractions. To find equivalent fractions, you multiply or divide the numerator and denominator by the same number. Thus, to solve , note that the numerator (2) was multiplied by 3 in order to get 6. Then do the same to the denominator (3) to get n=9. This works well when the numerator and denominator of one fraction are multiples of the other fraction, but it is more difficult to do when they are not, as in the case of . In this case we multiply both sides of the equation by 8n as shown below:
|(multiplying both sides by 8n)|
|(divide out the common factors)|
|(divide both sides by 6)|
Suffocate (5): (verb): to strangle

Reading involves an interaction between a specific type of text or written material and a reader who has a purpose for reading that is related to the type of text and the context of the reading situation.
The three purposes for reading are:
Reading for literary purpose
Reading to gain information
Reading to perform a task
Reading for literary purpose:
Reading for literary experience involves reading literary text to explore the human condition, to relate narrative events with personal experience, and to consider the interplay in the selection among emotions, events, and possibilities.
Reading to gain information:
Reading to gain information involves reading informative passages in order to obtain some general or specific information. This often requires a more practical approach to reading that requires the use of certain reading/thinking strategies different from those used for other purposes. In addition, reading to gain information often involves reading and interpreting aids such as charts, graphs, maps, and tables that provide data.
Reading to perform a task:
Reading to perform a task involves reading various types of materials for the purpose of applying the information or directions in completing a specific task. The reader’s purpose for gaining meaning extends beyond understanding the text to include the accomplishment of a certain activity.

Whole numbers are the counting numbers including 0. For example, 1, 2, 3, and 108 are wholes numbers. 3.5, 4.009, and Pi are not whole numbers.
Whole numbers greater than zero are called positive integers.
Whole number less than zero are called negative integers.
Use the number line for adding and subtracting integers:
• Add a positive integer by moving to the right on the number line
• Add a negative integer by moving to the left on the number line
• Subtract an integer by adding its opposite
We can use the number line as a model to help us visualize adding and subtracting of signed integers. Just think of addition and subtraction as directions on the number line. There are also several rules and properties that define how to perform these basic operations.
**To add integers having the same sign, keep the same sign and add the absolute value of each number.
**To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest.
**Subtract an integer by adding its opposite.
Here's how to add two positive integers:
4 + 7 = ?
If you start at positive four on the number line and move seven units to the right, you end up at positive eleven. Also, these integers have the same sign, so you can just keep the sign and add their absolute values, to get the same answer, positive eleven.
Here's how to add two negative integers:
-4 + (-8) = ?
If you start at negative four on the number line and move eight units to the left, you end up at negative twelve. Also, these integers have the same sign, so you can just keep the negative sign and add their absolute values, to get the same answer, negative twelve.
Here's how to add a positive integer to a negative integer:
-3 + 6 = ?
If you start at negative three on the real number line and move six units to the right, you end up at positive three. Also, these integers have different signs, so keep the sign from the integer having the greatest absolute value and subtract the smallest absolute value from the largest.
Subtract three from six and keep the positive sign, again giving positive three.
Here's how to add a negative integer to a positive integer:
5 + (-8) = ?
If you start at positive five on the real number line and move eight units to the left, you end up at negative three. Also, these integers have different signs, so keep the sign from the integer having the greatest absolute value and subtract the smallest absolute value from the largest, or subtract five from eight and keep the negative sign, again giving negative three.
To subtract a number, add its opposite:
5 - 8 = ?
Because they give the same result, you can see that subtracting eight from five is equivalent to adding negative eight to positive five. The answer is - 3.
To subtract a number, add its opposite:
-3 - (-6) = ?
Because they give the same result, you can see that subtracting negative six from negative three is equivalent to adding positive six to negative three. The answer is 3.
