The traditional counting system used in the Welsh language is vigesimal,
i.e. based on twenties as in the French numerals for 60-99, where numbers
from 11–14 are "x on ten", 16–19 are "x on fifteen" (though 18 is more
usually "two nines"); numbers from 21–39 are "1–19 on twenty", 40 is "two
twenty", 60 is "three twenty", etc.

There is also a decimal counting system, which is widely used, especially
in Patagonian Welsh[citation needed], where numbers are "x ten y" unit(s),
e.g. thirty-five in decimal is tri deg pump (three ten five) while in
vigesimal it is pymtheg ar hugain (fifteen – itself "five-ten" – on twenty).

decimal system rather than the traditional method is in everyday use in
