ADDING INTEGERSADDING INTEGERS
Positive + Positive = PositivePositive + Positive = Positive ( +3) + (+2) = +5( +3) + (+2) = +5
When a number is positive, you When a number is positive, you do not have to use the (+) sign.do not have to use the (+) sign.
(+3) + (+2) = 5(+3) + (+2) = 5
ADDING TWO NEGATIVE ADDING TWO NEGATIVE NUMBERSNUMBERS
Negative + Negative = Negative + Negative = NegativeNegative
(- 6) + (- 3) = (- 6) + (- 3) = - 9- 9
When a number is NEGATIVE, When a number is NEGATIVE, you do have to use the (-) sign.you do have to use the (-) sign.
