We've been over this alrteady :) The answer is always a multiple of 9 (including 0), so it just makes those the same symbol every time and it's right.

I new there was some sort of formula just could figure it out...

Alright, it looks like the math geek must strike again.

Any two digit number can be represented by 10x + y.

When you pick a two digit number and then subtract the sum, you get the following:

(10x + y) - (x + y)

Expanding you get:

10x + y - x - y

And finally:

9x

So, your answer will be the first digit of the number you picked multiplied by nine, regardless of what your second number was.
