your number can be expressed in the form 10x+y, e.g. 34 = (3x10)+4.
Then you subtract the first digit (i.e. x), and the second digit (y), so you perform:
10x + y - x - y = 9x.
Therefore the number you end up with will be a factor of 9. All the factors of 9 have the same symbol.

algebraic equations aside, how come you can keep getting different symbols?

it puts a different symbol there. To prove it to yourself, clicking on the bowl will always give the symbol at 9.

All multiples of nine have the same symbol which changes everytime you have a go. For example if 9 has a smiley face, so would 18, 27, 36 etc. The next round they would all change to a triangle or whatever. Basically all multiples of nine keep the same symbol. When one changes, they all do
