Multiplying With Negative Numbers

When multiplying with negative numbers, is the answer positive or negative? Here's a way to remember. (In this mnemonic, "good" is positive and "bad" is negative.)

  • A good thing happening to a good person is good. (Positive x positive = positive.)
  • A good thing happening to a bad person is bad. (Positive x negative = negative.)
  • A bad thing happening to a good person is bad. (Negative x positive = negative.)
  • A bad thing happening to a bad person is good. (Negative x negative = positive.)
