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.
