<P> The cardinal series are derived from cardinal numbers, such as the English one, two, three . The multiple series are based on adverbial numbers like the English once, twice, thrice . The distributives originally meant one each, two each or one by one, two by two, etc., though that meaning is now frequently lost . The ordinal series is based on ordinal numbers such as the English first, second, third . For numbers higher than 2, the ordinal forms are also used for fractions; only the fraction ⁄ has special forms . </P> <P> For the hundreds, there are competing forms: those in - gent -, from the original Latin, and those in - cent -, derived from centi - etc. plus the prefixes for 1--9 . </P> <Table> <Tr> <Th> Number </Th> <Th_colspan="4"> Latin prefixes </Th> <Th_colspan="3"> Greek prefixes * * </Th> <Th> Sanskrit </Th> </Tr> <Tr> <Th> Cardinal </Th> <Th> Multiple </Th> <Th> Distributive </Th> <Th> Ordinal </Th> <Th> Cardinal </Th> <Th> Multiple Proportional Quantitative </Th> <Th> Ordinal </Th> </Tr> <Tr> <Td> 0 </Td> <Td_colspan="3"> nulli -
