The word algebra is derived from the Arabic al-jebr, which means the restoring or reunion of broken parts. Its use in the West dates from the publication in the 9th century of Muhammad ibn Musa al-Khwarizmi’s Book of Restoring and Balancing. Khwarizimi’s name gave rise to the word algorithm. A classic discussion of the origins of algebra is given in Jourdain (1919).
