Arabic in full Muḥammad ibn Mūsā al-Khwārizmī
born с 780, Baghdad, Iraq
died с 850
Muslim mathematician and astronomer.
He lived in Baghdad during the golden age of Islamic science and, like Euclid , wrote mathematical books that collected and arranged the discoveries of earlier mathematicians. His Al-Kitāb al-mukhtaṣar fī ḥisāb al-jabr wa'l-muqābala ("The Compendious Book on Calculation by Completion and Balancing") is a compilation of rules for solving linear and quadratic equation s, as well as problems of geometry and proportion . Its translation into Latin in the 12th century provided the link between the great Hindu and Arab mathematicians and European scholars. A corruption of the book's title resulted in the word algebra ; a corruption of the author's own name resulted in the term algorithm .
