I'm wondering if anyone would know anything about Egyptian mathematics in a prehistorical setting. I've been reading mixed answers, with Egyptians using base 10 or base 12, (interestingly, without them using zero sometimes, which goes on to complicate things.
My question is what base the ancient Egyptians used? How did they come to using it? Did they in fact have the concept zero expressed? How has it affected modern mathematics/society as a whole (if it has)?
