       Some #linguistics / #ethnomathematicsIn most Eurasian languages, the numbers from 21 to 99 folllow the general pattern "X tens [and] Y".In Finnish: 42 = neljä·kymmentä·kaksi 'four tens two'However, in Finnic and Sámi languages (and probably in other Uralic languages as well), there used to be another system that used ordinals for the tens (and sometimes even for the hundreds):42 = kaksi·viidettä[kymmentä] 'two of the fifth [ten]'This approach would make it possible to have an unambiguous place-value number system without a zero symbol:III I II III'three of the first ten of the second hundred of the third thousand'= 2103

       @viznut : do you know that, in French, 80 is pronounced as "Four Twenties". And that 70 and 90 are pronounced as "60 10" and "80 10".So, in France, "99" is pronounced as "4 20 10 9".Which makes it impossible to spell out loud a phone number without ambiguity.(In Switzerland, this is not the case and Belgium is an hybrid with only "80" being pronounced as "4 20")
