## Rethinking Money (Again)

You know, now that we have the whole idea of putting money in different denominations on the table, I realize there’s no need to reduce it to powers-of-two the way computer programmers think makes sense. Really any set of relatively prime numbers will do just fine in terms of being able to make amounts of money you really don’t need, because the charge at most convenience stores is \$2.92 if you’re there at breakfast time, \$11.25 if you’re there in the afternoon or evening picking up a few things, and at the fast food place is pretty much going to be \$7.14 for lunch plus another \$1.42 if you go back for a McFlurry after.

So since we’re completely free to choose, let me design a set of currency that comes in denominations of 3, 7, 11, 24, 31, and 55 dollars, with additional bills worth negative two, negative thirteen, and negative twenty-nine dollars to make the vending machines happy. That should fix things.

## You Can Send Me Any Obsoleted Bills For Responsible Care

You know, it’s just a convention that we (I’m talking here about the United States) put out money in denominations of one and five and ten and twenty dollars, plus some other highly fictional amounts like fifty or a hundred or even two dollars. There’s no reason we couldn’t do it in a more orderly fashion, by which is meant the way computer programmers would do it, which is in denominations of one, two, four, eight, sixteen, and so on. Then an ordinary transaction could be much more logically handled, like this:

“Hundred and forty dollars, all right … uh … here’s a 64-dollar bill, and … 140 minus 64 is … more than 64, right? Well, I guess I have a 32 here and that’s … 140 minus 32 is … wait, 32 and 64 is … something and then that away from 140 is … uh … I could swear I had a couple 8-dollar bills when I set out this morning and … uh … OK, 140 minus 64 has to be like 86 … 76, thanks, and then from that I take away 32 and … no, I put in 32 and … ”

All right, so we’d have a couple more people who finish buying things at the supermarket by curling up in a ball and weeping, but that’s why the rest of us have credit cards for crying out loud.
