It's easy to pick on the weirdness of french numbers, but honestly "quatre-vingt" ends up just being a word like "eighty" in its own right. No French speaker is multiplying 20s in their head.

Probably the only true weirdness is the 70s and 90s because they use the teen words like douze and treize, but that's honestly where the weirdness ends, and larger numbers follow very consistent rules.
