Ohh oui, french numbers I think they go mental after 69 ( ͡° ͜ʖ ͡°)
70: 60+10 (soixante-dix)
91: 4x20+11 (quatre-vingt-onze)
Why? No clue I am not french.
May or may not have some relation, but next to France/part of, lies the Basque country, where all numbers under 100 are base 20+10, except 11 and 19...
57: 2×20+10+7 (berr-ogei-ta-hama-zazpi)
79: 3×20+19 (hiru-r-ogei-ta-hemeretzi)
French (in Belgium, Switzerland, and former colonies) also allows simple base 10:
70: 70 (septante)
91: 90+1 (nonante-et-un)
...so the geographic location seems to have an impact.
And just next to it, in Spain, everything is base 10... except 11 to 15 change the order from n×10+m, into 1+10 to 5+10.
Italian does the same, except it's 11 to 16... just like in French.
English has a hiccup with eleven and twelve, then goes to n-teen, before going base 10 with n×10+m above 20.
German does the same, except it goes to m+n×10 above 20.
Overall, 20 seems to be a magic number, France just seems to have mixed in different ways of using it.
