There are several similar variants of different kinds of math that make just as much sense as mainstream methods to me. It all feels very arbitrary. I think th

  But it's the same thing with math. All of science and engineering can be seen as useful artifacts that you obtain as a bonus from math.

    Yeah, or air. Besides, there's plenty more to science and engineering than just math.

  Maybe start using Roman numerals then?
  • codr7 2y ago
    Roman numerals are obviously inferior, not a fair comparison at all.

      Roman numerals were designed for a world where calculations were done on an abacus, and numerical systems merely recorded inputs and outputs. In that world they are better than Arabic numerals, for the simple reason that your brain doesn't have to translate so hard between what you see, and what you record.

        Also, this is how mental arithmetic is taught in modern elementary schools! Lots of focus on "ten friends", and performing addition and subtraction by splitting into parts to make "ten" and then adding or subtracting the leftover: 8+5 = 8 + (10-8) + 5 - (10-8) = 10 + (5-2) = 10+3 = 13 13-5 = 10 + (3-5) = 10 + -(5-3) = 10-2 = 8 The weird parts of Roman numerals is the lack of clear place value separation (no spacing, variable-length places I, II, VIII, etc), and using 5 V and 10 X so 2 different scales for place value, and the asymmetry of I,II,III,IV, V instead of the more consistent I,II,IIV,IV,V, and using relative position for sign instead of an explicit negative sign symbol.

      It wasn't obvious for the people who used them. And that's the point.

        Yes but I'm talking about several alternative systems existing in parallel, not something that can be blamed on time.
