Numerals Overview The Danish numbers are: Vigesimal system Counting above forty is in part based on a base 20 number system, called vigesimal: halvtred-s(inds-tyve) = 2 x 20, tre-s(inds-tyve) = 3 x 20, halvfjerd-s(inds-tyve) = 3 x 20, fir-s(inds-tyve) = 4 x 20, halvfem-s(inds-tyve) = 4 x 20 (halvtredje, halvfjerde and halvfemte (lit. "halfthird", "halffourth" and halffifth") being old words for 2, 3 and 4). This is unlike Swedish and Norwegian, both of which use a decimal system. The word fyrre / fyrretyve = "40" does not belong to the vigesimal system. The optional second part of the word is not the number tyve, "20", but an old plural of ti, "ten" (like in English forty, German vierzig); the first part is a variant of the number fire, "four". Similarly, tredive is a compound of tre, "three", and a weakened form of the old plural of ti, "ten". Vigesimal systems are known in several European languages: French, Breton, Welsh, Albanian, and Basque. Some scholars speculate that the system belongs to an "Old European" (i.e. pre-Indo-European) substratum, whereas others argue that the system is a recent innovation of the Middle Ages. See Vigesimal. Sequence of numbers The ones are placed before the tens with an intervening og ("and"): toogfyrre (42), seksoghalvfjers (76). The ones and the tens are placed after the hundreds with an optional og: to hundred (og) femoghalvfjers. This system is similar to that of German
