That's cool. I just don't do math on Pick 3 numbers because they're not numbers because they don't stand for anything. If they replaced the numbers with graphic symbols, Star - X - Palm - Cloverleaf - Comet - Cup - Key - Treasure Chest - O - Tophat, it wouldn't change a thing, except that it would be harder to track on a computer. But you wouldn't try to do math on Cup-X-Comet, would you? However, if they replaced the numbers with letters, A - B - C - D - E - F - G - H - I - J, all of my programs would still work because I treat the P3 numbers as string symbols not numbers. So, I could go in and do a direct replacement of every digit in all my databases with letters, for example -
A for 0
B for 1
C for 2
D for 3
E for 4
F for 5
G for 6
H for 7
I for 8
J for 9
and all my software (even my "Deflate" program, believe it or not) would still run exactly the same, except it would find exact sequences of letter string symbols instead of digits. That's shocking to hear, isn't it, but this was all done on purpose from the beginning.
I did this on purpose because a mathematician friend explained this whole thing to me, lo, those many years ago (almost 20 years now), but he wasn't willing to rule out the possibility that there might be patterns in the symbols, so that's the direction I went. I'm sure he'd be highly amused to see how far I took it, but that's what happened.
If you want to do arithmetic on the numbers, that's a-okay with me, but the above explains why I don't.
P.S. Someone could well ask, "Why do I look at digits of Pi as I did above?" My answer is, "I have no idea what the digits of transcendental numbers really mean." I'm not being glib. I really don't. The reason why I poked around in Pi to begin with was because I wondered if somebody somewhere might be manipulating the lottery "numbers" in some unimaginative way using Pi as a pad...
