@infobeautiful I found a decent explanation of the Danish approach: https://raufaliev.com/2025/04/17/unraveling-danish-numerical-peculiarities-april-17-2025-1658/

@infobeautiful FREAKS ME OUT

@infobeautiful Germans are confused and have spread their confusion. But not as confused as the French. And the Danes are just mad. 🤪

@infobeautiful Well, 97-99 would be even more complex in French:
4 x 20 + 10 + (7-9)

Still not as impressive as the Danish 🤣

@infobeautiful "..Il y a quelque chose de pourri au royaume du Danemark..." 🤣

@infobeautiful This should also separate out languages where 90 is transparently derived from those where it isn't (although that can be a gray area).

@infobeautiful 2 + 90 is kinda in line with "18" as "8 + 10".

@infobeautiful I love 🇩🇰.

@infobeautiful Everyone check on your Danish friends. They are not ok.

@infobeautiful Nice use of colour to subtly manipulate the reader

@infobeautiful in basque we also say 4*20+12

@infobeautiful "97-98-99" in French are even funnier : 4x10+10+7[or 8 or 9].

@infobeautiful Dialects in Norway that use the Nynorsk written dialect generally say 2+90 as they do in Germany and The Netherlands.

So both forms are used in Norway.

@infobeautiful This quirk of Danish language may explain why Denmark produces many more famous mathematicians and physicists than what you'd expect for its tiny size... 🤔

@infobeautiful In Norwegian Nynorsk the numbers after 20 are built in the same way as in German (én og tyve, ...)

@infobeautiful Russian is actually 100-9+2…

@infobeautiful noteable (apart from Denmark) is also the French I would not have expected the difference between French inside and outside France.

@infobeautiful Denmark is a joke, isn't it? Please. This can't be real.
