It even got reinvented by Alaskan Inupiaq speaking students recently derived the "Katuvik Numerals"... Maya had proper place-based base 20; Aztec didn't, but shares the same 1-19 symbols, and adds counters for 20, 400, and 8000...All of them, for the 1-19 symbols, use a 1's symbol up to 4 times (Maya/Aztec used dots, Inupiaq uses slanted verticals \ to \/\/) then a 5 symbol (Maya/Aztec a bar; Inupiaq a hoizontal slash); additional 1-4 and 5's until 19 (Maya/Aztec 3 bars under 4 dots; Inupiaq 3 mostly horizontal slashes above 4 mostly vertical ones). Katuvik and Maya both have a 0 symbol. All three are orally base 20 systems. There are others; many European languages 1st Millenium CE used base 20 as 1's and 10's orally, and roman numerals for writing...Many Eastern European languages used alphabetic characters as numbers... Slavonic and classical Greek both use the first 9 letters as 1-9, the next 9 as 10-90, the next 9 as 100-900... but wait, we all know greek only has 24 letters... which is why the archaic digamma (6, between epsilon and zeta), Qoppa (90, between pi and rho), and sampi (900, after omega); it also puts a marker after a number to indicate it is, in fact, a number and not a word. Slavonic has an amplicity of letters, and has distinct decorators for thousands, to millions... but the number order is jumbled because it's retained from the greek roots...(ancient greek, by contrast, has a discrete 1, 5, 10, 50, 100, 500, 1000, 5000, 10000, 50000 counters, not unlike Rome...)</blockquote>
