Rules for Multiplying Integers Multiply the numbers Same signs, answer is positive. Different signs, answer is negative. Rules for Dividing Integers Divide the numbers Same signs, answer is positive. Different signs, answer is negative.

Examples with Multiplication 5 × 4 = 5 × -4 = -5 × -4 = -5 × 4 = 20 (Same signs, answer is positive) -20 (Different signs, answer is negative) 20 (Same signs, answer is positive) -20 (Different signs, answer is negative)

Examples with Division 7 (Same signs, answer is positive) 21 ÷ 3 = 21 ÷ -3 = -21 ÷ -3 = -21 ÷ 3 = -7 (Different signs, answer is negative) 7 (Same signs, answer is positive) -7 (Different signs, answer is negative)
