The first number you chose can be written as 10*A +B, where A and B
are the digits of the number. They then ask you to subtract (A+B)
10*A + B - A - B = 9*A
All the multiples of 9 up to 81 in the chart have the same symbol.
Note that he populates the chart differently each time, so when you
try it again, a different symbol shows as the answer, enhancing the
illusion that it is guessing a symbol you seemed to have chosen at
random.

Okay, but it is still slick. (thanks for the explanation; I missed that
symbols change each time...)
