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:
Like signs positive: -3 -2 = 6 = 6 Unlike signs negative -4 7 = -28 = -7

Multiplication and division use the same rules:
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 = -34 + -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 - -89 – 2-7 - 4
-6 + 8 = 29 + -2 = 7-7 + -4 = -11
MULTIPLICATION AND DIVISION
- Multiplication and division use the same rules:
- Like signs positive: 9 3 = 27 -3 -2 = 6= 5= 6
- Unlike signs negative -4 7 = -288 -2 = -16 = -7= -6
