Multiplying two 2 digit numbers difference of 8
  • Example:

      1.If the first number is 34, choose 26 as the second number (8 smaller).
      2.The middle number (the average) is 30.
      3.Square this middle number: 30 x 30 = 900.
      4.Subtract 16 from this square: 900 - 16 = 884.
      5.So 34 x26 = 884.

  • See the pattern?

      1.If the first number is 64, choose 72 as the second number (8 larger).
      2.The middle number (the average) is 68.
      3.Square this middle number: 68 x 68 = 4624. Remember how to square a 2-digit number ending in 8?
      4.Subtract 16 from this square: 4624 - 16 = 4608.
      5.So 64 x 72 = 4608.

    Choose the second number that will give you the easier square, and use your square shortcuts. Practice.
