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
