How lame. The symbol which appears is above all the numbers in the 9 times table. 9, 18, 27 etc.
Pah! Call yourself a mystery!
I think it's great! I'm definitely going to try it on my children!
why is it that when you add up the digits and then subtract them you get a multiple of nine? Numbers can be really beautiful!
just clicked: 10a + b - ( a + b ) = 9a so the answer will always be nine times the first digit, which will also always be a multiple of 9.
