Oh jesus . . . okay, that's Rachel-Joe mind-meld matchup # googol. I did the same damn thing to pass time in gym or during high-school Nuremburg rallies. I'd stare at the clock and put the numbers together. Figured out that you could add 9 to any number x, get a new number y, and if you took apart the digits of x and those of y and added them together (separately, I mean), they'd be the same. To wit:

9 + 15 = 24
1 + 5 = 6
2 + 4 = 6

Me physics teach made us erase all the good programs, too (remember Race? and . . . a few others I'm forgetting), but someone always saved 'em as a backup.

I come from the days when QBasic was still a viable programming language for good teenage geeks, and my friend David still has the Huck Finn trivia program we made for our tenth-grade English project. (Public school teachers can get desperate for ideas sometimes.)
