Since this has a factual answer, I'll move it to GQ for you.

Once you add the sum of any two didgit number, and the subtract that sum from the original, it's always a multiple of nine.

The only possible numbers are:

81
72
63
54
45
36
27
18
9

And those are always the same symbols

Your link is taking forever to load for me, but it sounds like the same thing Snopes describes here (http://www.snopes.com/humor/iftrue/psychic.htm).
