Can you figure out how they do it?


Run several 2 digit numbers through your head like they want, but pick numbers widely spaced. Notice anything about the results?

13 > 1+3 = 4, 13-4 = 9
38 > 3+8 = 11, 38 -11 = 27
75 > 7+5 = 12, 75 - 12 = 63

Notice it now? They're all multiples of nine.

Now look at the chart - all the multiples of nine have the same symbol. It is a mathematical trick. I thought it was kind of neat. ;-)
