Some of you may know, that in Denmark tens and units digits are reversed, like in German or Old english (ref. "Four-and-Twenty Virgins" (trad.)). Also, numerals from 40 through 90 are based on a vigidesimal system. This means that the score is used as a base unit in counting:Tres (short for tre-sinds-tyve meaning "three times twenty") means sixty, while halvtreds (short for halvtredje-sinds-tyve meaning "half third times twenty", implying two score plus half of the third score) is fifty. Easy, isn't it? To make it more clear, the numeral halvanden means one plus half of the second one nad numerals halvtredje and halvfjerde likewise. Then Fifty-two is usually rendered as tooghalvtreds anf fifty-second is of course tooghalvtredsindstyvende.
