    I had to look this up. What the fuck? They came up with numbers up to 60 and then just said “eh, fuck it” and made 70 “sixty-ten”, 80 “four-twenties” and 90 “four twenties ten”.

      In Switzerland, they use septante, huitante, and nonante for 70, 80, and 90, respectively. Much more sensical, imo.

        In Belgium, they use “septante” and “nonante” too. 80 is still “quatre-vingt”.

      The other way around. We started with base 20 everywhere then simplified some of it.

      During medieval times it used to be :
      10 Dix (10)
      20 Vingt (20)
      30 Vingt et dix (20+10)
      40 Deux-vingt (2x20)
      50 Deux-vingt et dix (2x20+10)
      60 Trois-vingt (3x20)
      70 Trois-vingt et dix (3x20+10)
      80 Quatre-vingt (4x20)
      90 Quatre-vingt et dix (4x20+10)

      Then they switched to base 10… But only up to 70 for some reasons in France. Belgium and Switzerland (and some parts of France) have gone all the way to 100 by using Septante (70), Octante or Huitante (80) and Nonante (90).

      We’re not that different with the teens. We effectively say “seven ten”, “eight ten”, “nine ten”. You don’t think of nineteen as “nine+ten”, it’s just its own number. Well, the French take that one step farther.
