Adding Integers

·        When adding same sign we add their absolute values and give result the same sign.
·        When adding opposite sign, we take their absolute values,  

subtract  the smaller from the larger, and give the result the sing of the integer with the largest value.
Ex. 8+ (-3
    =8-3
    =5

 Subtracting Integers

Step 1.Change the subtraction sign into an addition sign.

Step 2.Change the sing in front of the second number.
Ex1. (+2)  – (+3) = -1    (+2) + (-3) = -1

 Multiplying Integers

+ x  + = +
-  x  -  = +
+ x  -  =  -
-  x  + =  -

Ex1. (+4) (+3) = +12    Ex2. (+2) (-3) = -6

Dividing Integers

Same thing as multiplying integers but you divide instead of multiplying  

+ /  + = +
-  /  -  = +
+ /  -  =  -
-  /  + =  -


Ex1. (+4) / (+2) = +2    Ex2. (-4)  / (+2) = -2
