Adding Integers Worksheets

Worksheets are below. How to add, subtract, multiply and divide with positive and negative numbers.
Adding Rules:
Positive + Positive = Positive 5 + 4 = 9
Negative + Negative = Negative (- 7) + (- 2) = - 9
Sum of a negative and a positive number
Use the sign of the larger number and subtract
(- 7) + 4 = -3
6 + (-9) = - 3
(- 3) + 7 = 4
5 + ( -3) = 2.
Subtracting Rules:
Negative - Positive = Negative (- 5) - 3 = -5 + (-3) = -8
Positive - Negative = Positive + Positive =
Positive 5 - (-3) = 5 + 3 = 8
Negative - Negative = Negative + Positive =
Use the sign of the larger number and subtract
(Change double negatives to a positive shown in red.)
(-5) - (-3) = ( -5) + 3 = -2
(-3) - ( -5) = (-3) + 5 = 2
Multiplying Rules
Positive x Positive = Positive 3 x 2 = 6
Negative x Negative = Positive (-2) x (-8) = 16
Negative x Positive = Negative (-3) x 4 = -12
Positive x Negative = Negative 3 x (-4) = -12
Dividing Rules
Positive ÷ Positive = Positive 12 ÷ 3 = 4
Negative ÷ Negative = Positive (-12) ÷ (-3) = 4
Negative ÷ Positive = Negative (-12) ÷ 3 = -4
Positive ÷ Negative = Negative 12 ÷ (-3) = -4
