# very simple, old trick
9, 18, 27, 36, etc. are always the same symbol. You always get a multiple of nine in the result...

11. 1+1 = 2, 11-2 = 9
12. 1+2 = 3, 12-3 = 9
13. 1+3 = 4, 13-4 = 9

and so on.

i figured that the silly sum had to be the key, so i just put consecutive numbers into the formula, and noticed the pattern.
