¹ Our word *algebra* is from the title of one of his works, *Al-jabr wa'l-muqābalah*, Completion and Comparison. The work was translated into English by F. Rosen, London, 1831, and treated in *L'Algèbre d'al-Khārizmi et les méthodes indienne et grecque*, Léon Rodet, Paris, 1878, extract from the *Journal Asiatique*. For the derivation of the word *algebra*, see Cossali, *Scritti Inediti*, pp. 381–383, Rome, 1857; Leonardo's *Liber Abbaci* (1202), p. 410, Rome, 1857; both published by B. Boncompagni. "Almuchabala" also was used as a name for algebra.
