Well, what do you expect from a computer programmer? I mean the whole thing just works on the fact that the answer is always divisible by 9...why, you ask?that was just nerdy

Man i think you are the smartest person on ca.com. Seriously, i wish i could cheat off you in school //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gifWell, what do you expect from a computer programmer?

XY - (X + Y)
= 10X + Y - (X + Y)
= 10X + Y - X - Y
= 10X - X
= 9X, or the multiple of 9 that's in the 10s place value
Believe it or not, I do these things to keep my mind "fresh" when I'm out of school. Ever went back to school after summer break & your handwriting was just horrible?
