In as much as it helps me understand chemistry, which is truly cool... yeah, math is OK. Math is cool? In as much as it helps me understand chemistry, which is truly cool… yeah, math is OK.

Any math problem that triggers my interest enough to make me interrupt a steno-pad-page full of to-dos and work it out is a good one :) ...and I still have to figure out why the "add 1" is in there!

…and I still have to figure out why the “add 1″ is in there!

That sets it up to look like your phone number, but have 0's instead of the last four digits. You'll of course add them in later! The multiplication by 2 is just to make the whole thing cooler. I think (but don't have time to prove right now) that you add 1 just before you multiply by 250 so that it works out when you eventually subtract out 250. Then, you add the last four digits twice (so when you divide by 2 it comes out right). Now subtract 250, which takes care of the 1 you added earlier. Dividing by 2 gives you your number. Sorry -- just love seeing the math behind these.... Okay, here comes the mathematics major to ruin it all
