Integer – positive & negative numbers Adding -2 + 3 = 1 + 2 = -3 + 1 = 1 2 3 4 -1 -2 -3 -4 1 3 -2

Integer – positive & negative numbers Subtracting 2 - 3 = -1 - 2 = -1 - - 2 = 2 - + 1 = 1 2 3 4 -1 -2 -3 -4 -1 + -3 - 1 1

Adding Subtracting Integers Try 0 - +3 = 0 - 3 = -3 1 + -2 = 1 - 2 = -1 -3 - - 5 = - 3 + 5 = +2
