How does it do it?

EDIT: Just learned how to do spoilers from the Wii thread!
Any 2 digit number minus its digits is a multiple of 9. The junk on every multiple of 9 is the same.

If this is right, then if the math problem is done correctly the junk genie will always be right no matter what.

Looking through this thread, an alarmingly large amount of people on UF suck at math.

It is always right no matter what, and this thing is older than the sun.

And like you said, if it gets yours "wrong" it's because you can't calculate your way out of a wet paper sack.
 
If this is true than it doesn't make any sense that you would get different answers at all, it would always produce the same answer. It doesn't.

There is no "if" this is true. This is true. It is an undeniable fact of nature. Math is not subject to interpretation. You did the math wrong, or looked at the wrong box.

Showing that any two digit number less the sum of the two digits is divisible by nine (whole positive integers only of course).

(10x + y) :: Two digit number

(10x + y) - (x + y) :: Subtract the sum of the two digits

= 10x + y - x - y :: Associative property (not sure)

= 10x - x :: (y) + (-y) = 0

= 9x :: Subtraction. 9x is obviously divisible by nine.

Edit: Or the program screwed up. But not God the universe and math.

Edit: In base 10.
