Multiplying & Dividing Integers

Same signs give a positive answer; different signs give a negative answer.

Step 1 · Learn

Walkthrough

Read this first — it covers the idea in plain language with a worked example.

One rule for both operations

Multiplication and division follow the exact same sign rule, so you only have to remember one thing.

  1. 1Same signs (+ and +, or - and -) → the answer is positive.
  2. 2Different signs (+ and -) → the answer is negative.
Worked example

Evaluate (-6) × (-4) and (-20) ÷ 5.

  1. →(-6) × (-4): same signs → positive. 6 × 4 = 24, so the answer is 24.
  2. →(-20) ÷ 5: different signs → negative. 20 ÷ 5 = 4, so the answer is -4.

Tip

Count the negative signs. An even number of negatives gives a positive; an odd number gives a negative.
