If you forget the product of 9 and 9, what can you do to figure it out?

  1. 0
  2. 7
asked by Alexandra
  1. Use a calculator.

    Or better yet -- remember that the digits of the product or 9 times any number will always add up to 9.

    18, 27, 36, 45, 54, 63, 72, 81, 90

    Another way is to multiply 9 * 10 = 90 and subtract 9 from 90.
