🇬🇧: 90+7 (ok, there is some jank in English numbers - 13-19 are in line with the Germanic pronunciation, i.e. pronounced "right to left", as a weird hold-over from the more Germanic Old English)
🇪🇸: 90+7
🇩🇪: 7+90
🇫🇷: 4x20+10+7
And if you think that's bad, the Danes actually make the French look sane...
🇩🇰: 7+(-½+5)x20
Even Danes generally don't really know why their numbers are like that, they just remember and go along with it.
While learning Danish I figured out that's just the arcane incantation for the number. It's language juju, and you just have to know that it be like it do. Yes, it's syv og halvfems, but the reason behind it doesn't matter anymore. The rest of the double digit numbers are a mess as well; 30 is tredive (three tens in old norse) but starting with 50 it's this weird score (20) and half-to-score system.
When I first started learning my brain was desperately trying to make heads or tails of it and rationalize it somehow. And then I realized that was stupid, abandoned reason, and now I just utter these backwards ass numbers and we all nod and everyone is happy lol. Language is weird.
