Back of Stela C > the Olmec independently invented the concept of zero. The second earliest found instance of the use of zero—in Mesoamerica—has been dated to 32 B.C. by the Epi-Olmec culture. This date has been arrived at based off the Long Count date on Stela C at Tres Zapotes. The symbol used for "zero" is a shell glyph, which is seen on the stone carving. Although the Olmec didn't leave behind any statues or reliefs with a "zero" glyph, the use of the Long Count calender requires the knowledge of this concept since it's based off the Vigesimal number system, which the Olmec are credited to have created.

I don’t get the cultural glazing of the number 100. I understand liking 5 and 10 as humans, (digits are cool, got 5 per limb, 10 fingers, 20 digits total) but 10^2 seems arbitrary and unnecessarily granular for how common percentages are.

I propose - solving nothing and frustrating everyone - swapping to a base 20 system of odds called perVentage. I’m not 20 pervent on that though, maybe ten pervent at best, a 10/10 crapshot.

I mean, take it further and just base 20 everything. Starting now.

*ehem* I propose - solving nothing and frustrating everyone - swapping to a base 10 system of odds called perVentage. I’m not 10 pervent on that though, maybe ten pervent at best, an a/a crapshot.

9:20 -- When a Number System Loses Uniqueness: The Case of the Maya

*13 days a week, 20 days a month, 365 days a year *Base 20 number system  **Third place value breaks cycle.  **18 x 20 =360 which is closer to 365 than 20 x 20 *1, 1x20, 1x18x20, 1x18x20^2, ... *5, 19, 0 + 1,0 = 6, 2, 0 since thirds place only has maximum 18 *5, 19, 0 = 6, 1, 0 and 5, 18, 0 = 6, 0, 0 --> non-uniqueness

Sora

Sora is a language in a tribal village in India that uses both a base 12 system and a base 20 system to count upwards from 1. The beauty of this is that as the numbers ascend, they use whichever base set they want to pronounce the number. Beautiful.
