regarding the math/magic site: if you check out any multiple of 9 the symbols are always the same. If you choose a number say ab, that is 10xa + b. For instance 98. That is 10 times 9 plus 8. Add 9 and 8 and that is 17. Take that away from 98 and that is then 81. The result will always be a multiple of 9 and each time you check your results the symbol for all the multiples of 9 will be the same, they do change each time so that you will think it is "magic". ((10a+b)-(a+b)) will always be a multiple of 9 because that will always leave you with 9a or 9 times the first digit of the number you picked. Summertop is on top of it. OK, I'll shut up now.
