What's going on in Denmark?

I love this topic, keep the comments going! It gets even wilder/weirder when reading historical German monastary documents from the early modern period that sometimes mixed German numerical grammar with latin letters and abbreviations. For example this was a common way to write prices in the early 17th century in my region of study:

xiv C Lviұ f xxv bb iy d

All of this was in early modern German Kurrent (old cursive), of course, and with not always obvious whitespaces inbetween. The letters v and x looked somewhat similar, too, and you better don't miss the small strikethroughs anywhere in the lower or upper end of a letter which indicated "minus half" (except for the letter capital C which always has it). This is the kind of fun that brings me joy during my day while simultaneously providing the content for nightmares at night.

For some closure:
The short example would read as: (10+(5-1))*100 + 50+((5+3)-0.5) florin, 10+10+5 batzen, and 1+1+1 denari.
And that would translate to a price of 1457 ½ florin (guilders), 25 batzen (silver coin) and 3 denari (pennies).

In Hungary we don't even have a separate name for 11 and 12, just 10 + 1 and 10 + 2. But at least we messed up the billions, it's called 'milliárd' and the trillion is 'billió'. We were so close to making it perfect.

I think Denmark should stop doing crack.

Man and here I thought the English system was kinda screwy, where at first it's in base 12 and base 20 at the same time what with having special unique names for all digits up to twelve, and then thirteen through nineteen are also uniquely weird, then at twenty we decide "man fuck that" and then it's in base 10 until we repeat that pattern every 100, ie "one hundred seventeen." Or then we occasionally do stupid things like "seventeen hundred" instead of "one thousand seven hundred."

It just now hit me that "teenager" is an inherently English construct because that weird partial second decade we have. I'm curious, how does that work in languages? Like, in French they have special words up to 16 and only do "ten-seven, ten-eight, ten-nine." You spend seven years as a teenager in England but only three in France.

4*20+12

Four score and twelve

So what is going on in Walloon and Swiss French? Is it just the Parisian dialect that is messed up?

I’m not sure what’s more asinine, the colors chosen for this map, or the ~~Dutch~~ Danish.

Edit: worth it for the joke

Are all German numbers like that?

You missed the traditional Celtic systems.

Welsh should be both 9 x 10 + 2 and 2 + 10 + 4 * 20.

And Irish – I didn't get it, they seem to have a modern 9 x 10 + 2 system, an old vigesimal and one for age?

Impressive that Norway has bands of different ways to say 92!

I'll see you at twenty past nine

NL: oh you mean 10 before the half of 10

Czechia should also be a combination of both 90+2 and 2+90
