Multiplying A Repeating 3s Number By 88

Multiplying a repeating 3's number by 88

  1. Choose a repeating 3's number (333, etc.)
  2. Multiply it by 88
  3. The product is:
    - the first two digits are 29
    - the next digits are repeating 3's (two fewer than repeating 3's in the original number)
    - the last two digits are 04
   Example:
  1. First pick is 3333.
  2. Multiply by 88. The product is:
    first two digits are 29: 29.
    next digits are repeating 3's (two fewer than repeating 3's in the original number): 33.
    the last two digits are 04: 04.
  3. So 3333 × 88 = 293304.

   See the pattern?

  1. Next pick is 3333333.
  2. Multiply by 88. The product is:
    first two digits are 29: 29.
    next digits are repeating 3's (two fewer than repeating 3's in the original number): 33333.
    the last two digits are 04: 04.
  3. So 3333333 × 88 = 293333304.
