ADD SUBTRACT MULTIPLY DIVIDE To add integers with the same sign, add their absolute values. The sum is : Positive if both signs are positive. Negative if both signs are negative To subtract an integer, add its additive inverse. p – q = p + (-q) Multiply Integers with the same signs. The product is positive. Examples: 6 – 7 = 6 + (-7) 2-(-2) = -10 – (-7) = To add integers with different signs,subtract their absolute values. The sum is : Positive if the positive absolute value is larger. Negative if the negative absolute value is larger. Multiply Integers with different signs. The product is negative.
