Rule for multiplying and dividing integers with the same signs
SAME SIGNS- POSITIVE
Multiply the numbers. The answer will be positive.
Divide the numbers. The answer will be positive.
(-5) × (-5) = +25
(-5) ÷ (-5) = +1

Rule for adding integers with same signs
Add and keep the same. Positive + Positive = Positive
Rule for multiplying and dividing integers with DIFFERENT signs
DIFFERENT SIGNS- NEGATIVE
Divide the numbers. The answer will be negative
Multiply the numbers. The answer will be negative
(+5) ÷ (-5) = -1
(+5) x (-5) = -25
