Ok, you see a lot of these tricky sites on the www. But this… this is no run of the mill sawing off legs.
Do this and tell me how he does it. I’m thinking magic.

If you and Hal are stumped, I don’t feel so stupid.
There’s got to be limited combinations of numbers that result from the first part. I think something like 16 or so results. So take those 16 possible answers, reverse & subtract. Another 16 answers. Remove the zeros and there’s the possible results. I can’t sit down to do it, but I’m guessing the results are limited.
I tried three different combinations and noticed that after the subtraction, the resulting digits always added up to 9 (sometimes you have to keep adding until you’re down to a single digit, but that single digit was always 9). Now if you give me two or three digits, then I just add them together and subtract that from 9, and that tells me the one that’s missing. (I’m not going to submit this as a formal proof, but I think I’m heading in the right general direction of the answer.)
