The undecimal numeral system (also known as the base-11 numeral system) is a positional numeral system that uses eleven as its base. While no known society counts by elevens, two are purported to have done so: the Māori, one of the two Polynesian peoples of New Zealand, and the Pañgwa (Pangwa), a Bantu-speaking people of Tanzania. The idea of counting by elevens remains of interest for its relation to a traditional method of tally-counting practiced in Polynesia. During the French Revolution, base-11 was briefly mentioned as a possible basis for the reformed system of measurement. Base-11 numerals also appear in the International Standard Book Number system.
