    But why did we pick base 10, was it because we have 10 fingers? That little dude has 3 fingers per hand. Seems like they would end up using base 6 and design a whole system around that, and base 10 would be strange to them.

      Mostly because it’s very easy to make calculation on base 10. If i ask you to tell me how many millimeters are in 5.7 meters you could probably reply easily without a calculator. You probably wouldn’t do it as easily if it wasn’t base 10

        We define 1000 mm as one meter as we are base 10 centric. If we live in a base 8 world, we would have define 8x8x8 mm as one metre and the answer to 5.7 m base 8 would be 5700mm base 8 too

        It’s not fundamentally easier to do calculations in base 10. It’s only easier for us because that’s what we learn as children.

        If our number system was based on a superior base, like dozenal or senary, we would be able to do calculations on that base easily and would find working in tens awkward.
