Very interesting. Arrived for another post, but was sucked in by this one.

Doesn't matter what 2-digit number you choose, the algorithm always results in a multiple of 9. It's easier to see if you switch the order of numbers subtracted.

Subtracting the second digit from the 2-digit number always results in the next lowest multiple of 10. Any 2-digit number ending in a zero is equal to 10 x the first digit. Subtract the first digit once and you have 9 x the first digit.

Now look at all the multiples of 9 in the table. Notice anything?
