| To carry out their calculations, merchants in the early 13th century used an abacus or a system called finger reckoning. Commerce changed when Leonardo of Pisa -- known today as Fibonacci -- published the first arithmetic textbook. Mathematician Keith Devlin talks about the history of arithmetic and his new book The Man of Numbers: Fibonacci's Arithmetic Revolution. |
