Multiplying a repeating 9's number by 88

Follow the following Steps:

1. Choose a repeating 9's number (at least three digits long -- 999, etc.)
2. Multiply it by 88
3. The product is:
   - the first two digits are 87
   - the next digits are repeating 9's (two fewer than repeating 9's in the original number)
   - the last two digits are 12

   Example:

1. If the first number is 8888:
2. Multiply by 88. The product is:
   - the first two digits are 87: 87.
   - the next digits are repeating 9's (two fewer than repeating 9's in the original number): 99.
   - the last two digits are 12: 12.
3. So 9999 × 88 = 879912.

   See the pattern?

1. If the first number is 999999:
2. Multiply by 88. The product is:
   - the first two digits are 87: 87.
   - the next digits are repeating 9's (two fewer than repeating 9's in the original number): 9999.
   - the last two digits are 12: 12.
3. So 999999 × 88 = 87999912.
