Dividing a repeating 6-digit number by 7, 11,
                13; subtract 101

1. Select a 3-digit number.
2. Repeat these digits to make a 6-digit number.
3. Divide this 6-digit by 7, then 11, then 13.
4. Subtract 101.
5. The answer is the original number minus 101!

   Example:

1. If the 3-digit number selected is 289:
2. The 6-digit number is 289289.
3. Divide by 7, then by 11, then by 13:
   the answer is 289.
4. Subtract 101: 289 - 101 = 188
5. So 289289 divided by 7, then 11, then 13 minus 101 is 188.

   See the pattern?

1. If the 3-digit number selected is 983:
2. The 6-digit number is 983983.
3. Divide by 7, then by 11, then by 13:
   the answer is 983.
4. Subtract 101: 983 - 101 = 882
5. So 983983 divided by 7, then 11, then 13 minus 101 is 882.
