This is really cute, but I sent it around to all the folks I knew were
either math people or programmers, and Nancy Griffin said send it to
Edgerton. They made short work of it. I quickly noticed the nines and
multiples but didn't realize a thing all programmers and math folk know:
that any two numbers added together and then subtracted from the original
number yields a multiple of nine.
So you're always going to choose some multiple of nine. So all that's
necessary is for the programmer to assign the same symbol to all multiples
of nine, then, so you won't notice that, have them change each time to some
other (common) symbol.
As I said, cute.
