I mean, who thought it'd be good to organize things according to dozens?

Supposedly, Sumerians had their number system based off of the number sixty. I asked my father about it once and he said sixty was divisible by more numbers than ten, so it did sort of make sense. But why would having more multiples be easier?

    Do you mean more factors?

      That is what I meant. I think. Been a while since grade school math (although you remember and you're older than me... I are stupids)

        The Romans. There was 12 ounces in a Roman pound and 12 pounds in a Roman stone. A carat of diamond is 1/144 Roman ounces. There was 12 lines in an inch and 12 inches in a foot. I could go on if you like. The old myth that you can't multiply in Roman numerals disappears if you know to work in 12s instead of 10s like you were taught.

          I thought the problem with multiplying in Roman numerals was their lack of positional notation?

            Again that is limiting the problem to our way of thinking. CXII = C + X + II so if you wish to multiply it by XIV you multiply (C+X+II).(X+IV) = C.X + C.IV + X.X + X.IV + II.X + II.IV = M + CD + C + XL + XX + IIX = MDLXIIX. You can make your life even easier thinking of IV as V - I.

              Thanks, Pi, good stuff. Can you illuminate me on the Sumerians?
