The "Magic" Gopher

Magic Gopher follow-up.

How does he do it?

If you make a chart of all possible answers, the only answers possible are multiples of 9:
9, 18, 27, 36, 45, 54, 63, 72, 81.

If you look at the chart of symbols, all of the multiples of nine have the same symbol. However, each time you do it, the symbols change, yet the multiples of nine all have the exact same symbol. So, no matter what number you choose, your answer will be a multiple of nine and will have the same symbol of any number you could start with.
