The Magical Number Nine (SOLUTION)
If you thought the number 9 was magical, well then you are wrong. This behaviour is simply a consequence of the base-ten number system that we use most often. Any whole number with 2+ digits can be broken into the sum of digits plus a multiple of 9. Repeating this process will end up with the smallest multiple of 9 possible, which is 9!
