    Personally i think 9 is the most interesting number.

    multiply any number by 9, add up the figures in the total (7 x 9 = 63; 6 +3 = 9) and you end up with a 9. Reverse the digits (36) and you always get a multiple of 9. Take any number - say 4,321 - and divide it by 9. The remainder (1) will be the same as you are left with when added together (4+3+2+1 = 10) and divided by 9.
