INTEGERS

ADDING INTERGERS


Step 1. If you have an addition problem you need to subtract the problem and keep the sign of the bigger number.

( DO NOT ALWAYS MAKE THE PROBLEM POSITIVE)
EX. -5 + 3= -2
Seem easy....... if not i will show a nother problem
EX. -7 + -3 = -10

do you see how i kept the sign of the bigger #?



ok we get addition now so we will move one step up .This was hard for me at first but i learned some helpul tricks to help out on those hard problems.

SUBTRACTING INTEGERS

The way to subtract integers is you have to do the (plus the oposite). That means you have to change the sign of the last # to the subtraction sign.

this might sound confusing at first but when you start to do some problems by yourself you will get the hang of it!
(remember always to do plus the opposite if you don't you will get the answer ALL WRONG!!!!!)

EX. -6 - 5 = NOW BEFORE I GET TO THE ANSWER YOU WANT TO CHANGE POSITIVE 5 TO A NEGITIVE 5.

SO as i was getting at -6 + -5=-11 %)) :$ !) :/


The next intger operation i will teach you is the MULTIPLICATION OPERATION!

The multiplocation operation is a little tricky, you haveto switch the operation of the number to equql a positive #.

You are probly a lttle confused right about now . What i said earlyer is if you have 2 positives or 2 negitives it will ALWAY BE A POSITIVE !!!!!!!!!!!!!!!!!!!!!!!!!!!!


EX. -5 . 3= -15
EX. -6. -2= 12
EX. 4 . 6=20

This was a pretty simpl concept for me but if you need some help on it jist remember my three simple rules.

1. If there is 1 negitive and one positive it will be the bigger of the two
2.if there are two negetives it will be a positive
3.if there are two positive it will also be a positive

Last but not least we ar going to divide

DIVIDING INTEGERS

WHEN Y DIVIDE INTEGERS YOU ALWAYS MULTIPLY THE NUMBER THAT WOULD MAKE IT A POSITIVE.

EX. 15/3 =5

YOU USE THE SAME THREE RULES FOR DIVISION AS YOU DO FOR MULTIPLACATION

HOW CHECK AND SOLVE AGEBRA





Solving the equations: First ask yourself what is being to your variable( you want to have your variable lonely and alone.Next do what scientists call invers opperation( the opposite opperationthat is shown).





EX. 4+x=7 STOP! Now since it is addition invers the opperation to subtraction. now to get back to the problum. :))



4+x=7

-4 x=-7

4

x=3

Easy right?





NOW WE ARE GOING TO SHOW YOU HOW TO CHECK THE PROBLUM



To solve the problum is a little easyer than checking it. To check the problums have more steps. first you want to rewrite the problum.(the exact way shown) Next you want to want to plug in the answer. then you MUST simplify your answer. your variable must equel your answer.





Ex. 3+x=7

3+4=7

7=7 STOP a quick tip is to put a check above the equal sign just to show that you now that the answer acutaly equaly is the right answer.

FACTORS

Factors are the numbers that a certan number can multiply into. You can also
use them to find the least comain factor of two or more numbers ( they both have
to be able to equal the same number)



ex. 12= 24,36, 48,60 answer: 24
8= 16,24,32

ex. 4=8,12, 16,20,24,28,32 answer:20
5=10,15,20

easy righ?If you dont get this concept take a look at my website link to get extra help and if you dont get it after that you might want to get some help...... yeah thats what you should do. After your done look at the rest of my blog! :)

KRUNK JUICE!!!!!!!!!!!!!!!!









6-O UNDEFEATED YEAH! :)) :() %)............... THAT LAST ONE WAS A LITTLE CREEPY.

Exponents and scientific notation

SCIENTIFIC NOTATION
To do scientific notation you have to make a decimal into a regular number by counting the number of zeros in the number and moving the decimal that many spaces. It should end up at behind the first in the number. You know how many spaces also by looking at the exponent.
EX. 5.43x ten to the third power =5,430
EXPONENTS
The base is the number that you multiply however many times the exponent wants you to and the exponent is the number that is how many times you are going to multiply the base.

EX. 4 to the third power or (4x4x4)=64


Exponents
Before we dive into simplifying exponents, let's take some time to learn exactly what an exponent is. An exponent is a superscript, or small number written at the top right corner of a number, variable, or set of parentheses. An example of one is shown below.
23
This tells you to multiply 1 by the number as many times as the exponent says. The example above is 2 raised to the third power (raised to the third power means the exponent is 3). This is equivalent to the multiplication problem below, because there is a 1 multiplied by 2 three times.
1 * 2 * 2 * 28
As you can see, the 1 * 2 * 2 * 2 can be simplified to 8 which is the answer to the problem.(http://www.algebrahelp.com/lessons/simplifying/numberexp/)
