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
