Well, how does it work?

I noticed one thing though.
The examples they give you for the two digit number (23, 46, 84) come out as the same sign for a random number that you picked. The answer to them are 23 = 18, 46 = 36, 84 = 72
Heres what I mean.
I pick 25. 2+5=7, 25-7=18
The number 18 would be the same sign as 36 and 72. The same answer as the examples.

Nevermind, I found out.

9, 18, 27, 36, 45, 54, 63, 72, 81

When the equation it done all two digit numbers will equal one of thoes number. For thoes numbers ther are the same sign. Get it?
