Ok I got it, all the possible answers always have the same symbol but they change which symbol it is each round. Hope that made sense.

You are always going to get the first digit less of the whole number... so if you pick a number in the 20's you are always going to get 2 less than 20 ie.. 18.. if you pick a number in the 50's you are always going to get 5 less than 50 ie.. 45.. so it just puts the same symbol on all nine possible answers... which are 81,72,63,54,45,36,27,18,9

The random double-digit number is 10a + b where a is the first digit and b is the second digit (for example if we take 56 then a = 5 and b = 6). Then in the end we get (10a + b) - (a + b) which equals 9a. The answer is always a multiple of 9.
But it's the fact that the table changes every time that makes this trick work.
