    Just write out the trick as an equation:

    10x + y - (x + y)
    = 10x + y - x - y
    = 9x

    You always get a multiple of 9. So the 9th symbol is always the same.

    Hmmm, whatever number you pick, that calculation always ends up being a multiple of 9, and all the multiples of 9 have the same symbol next to them.
