I mean unless people had 6 fingers it would seem counter-intuitive to use any numbering system that does not have a base that is a multiple of 5. Or am I missing something?
In: Mathematics
Base 60 was used by the Sumerians
If you take your left hand and use only the knuckles of the fingers, ignore the thumb, you have 12
The other hand can be used as a multiplier.
