This is fascinating, thank you. The intricacies of languages is so interesting. I especially love the insane way we danes spell out numbers.

59 == nioghalvtredssindstyve

59 == 9 [ni] + [og] ((3 [treds] - 0,5 [halv]) * [sinds] 20 [tyve])

So 9+2,5*20 == 59

Halvtreds means half third, or halfway to three. There's also halvfjerds and halvfems for 3,5 and 4,5. Exercise: spell out 79.
