Notes
1. As the only known alternative arithmetical operation beyond these fundamental ones, Greenberg refers to the so-called “going-on” operation, which is found in some Mayan and Finno-Ugric languages. Ostyak (Ugric, Uralic) expresses 18 as 8, 20, that is ‘8 going-on 20’. (Hurford 1975: 235 called this operation “over-counting”, which seems to be the more common expression; cf. Comrie 1997: 53).2. Cf. #1252.
