It basically works with the number 9. Any time you take a number, concatenate its digits together, and then subtract the sum of the digits from the concatenated number, you will get a number that is divisible by nine.
Since the computer chooses only those numbers that are divisible by 9, and it knows you will only choose a number that is divisible by nine, you will always have a match.
The computer changes which symbols are associated with which numbers to throw you off.

Because the answer, based on the numeric system we have, will always be a miltiple of nine. If you look at the code before you begin, all the multiples of nine have the same symbol associated with them, and the answer is always that symbol, though is changes each time so as not to give it away. It works with the same principle as this one...
Pick a number between 1 and 7.
Multiply by 9.
Add the digits.
Subtract 2.
Multiply by 9.
Add the digits.
Subtract 4.
Your result is 5, correct? It works every time.

This is the key to the trick right here. Without changing the symbols, it would be the same every time.
