ooh...how spooky that little sum (2 digit number, add together the digits, subtract from original number) will always give you a multiple of 9. the symbol next to 9,18,27,36,45,54,63,72, and 81 will always be the same.. DEAD spooky
every few months this site or a similar one pops up on the board, i always spoil everyones amazement in about 10 minutes
