The duodecimal numeration system refers to the base twelve system, which uses the symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, T, E.

Historically, a numeration system based on 12 is not new.
There were 12 tribes in Israel and 12 Apostles of Christ. In Babylon, 12 was used as a base for the numeration system before it was replaced by 60. In the 18th and 19th centuries, Charles XII of Sweden and Georg Buffon (1707–1788) advocated the adoption of the base twelve system. Even today there is a Dozenal (formerly Duodecimal) Society of America that advocates the adoption of this system. According to the Society’s literature, no one “who thought long enough—three to 17 minutes—to grasp the central idea of the duodecimal system ever failed to concede its superiority.” Study the duodecimal system from 3 to 17 minutes, and comment on whether you agree with the Society’s statement.
