Roman numerals had tally marks for
1-4, then a V for 5. I just read that in Maya writing, dots meant single units
and a bar represented 5.
I thought it was cool that 2
different ancient civilizations, on 2 different continents, marked off by 5. Is
it because we have 5 fingers on one hand? What’s the deal? Did anybody else do
it that way?
