INTEGER RULES
ADDITION
Like signs - add numbers; answer is same sign
6 + 5 = 11
-6 + -5 = -11
Unlike signs – subtract numbers; answer is same sign as larger number
–7 + 4 = -3 4 + -10 = -6
SUBTRACTION
“Keep it, Change it, Change it” Then use addition rules to solve:
-6 - -8 KCC -6 + 8 = 2
MULTIPLICATION/DIVISION
Multiplication and division use the same rules:
14
12
Like signs positive: -3  -2 = 6
=6
Unlike signs negative -4  7 = -28
= -7

INTEGER RULES
ADDITION


Like signs - add the numbers and use the same sign as both numbers
Ex. 6 + 5 = 11
-6 + -5 = -11
Unlike signs – subtract the numbers and use the same sign as the larger number
Ex. –7 + 4 = -3
4 + -10 = -6
SUBTRACTION

The phrase you want to keep in your head is “Keep it, Change it, Change it”
You keep the first sign, change the – to a +, and change the sign of the last integer.
Then use addition rules to solve. Here are some examples:
-6 - -8
9–2
-7 - 4
-6 + 8 = 2
9 + -2 = 7
-7 + -4 = -11
MULTIPLICATION AND DIVISION

Multiplication and division use the same rules:
