Is one of the early Muslim mathematicians, where his work contributed to a significant role in the progress of mathematics in his time
He worked at the the House of Wisdom in Baghdad and gain the confidence of the Caliph Mamoun and appointed at the Hikma house, he also was entrusted with drawing a map of the world. And before his death in 850 AD / 232 AH Akhawazrma left many of the books in the science of astronomy and geography of the most important algebra book, which is the most important book written has been translated into Latin in the year 1135 AD has subsequently entered words such as algebra and algebra zero zero to Latin languages​​.
His life
His family moved from the city of an algorithm (called'' Ckheoa'' in the current era, in the Republic of Uzbekistan) to Baghdad in Iraq, And he accomplished most of his research, between 813 and 833 in the House of Al-Hikma, which was founded by Caliph al-Ma'mun. Where Caliph al-Ma'mun appointed him as the head his of wardrobe books, and entrusted with the collection of Greek books their translation. Algorithm has benefited from the books that were available in a closet safe studied mathematics, geography, astronomy, history, as well as his knowledge of Greek and Indian. And dissemination of all his works in Arabic, which was the language of science in that era. Tabari and he calls in its history: Muhammad ibn Musa al-Khwarizmi Alqtrpley, relative to the village of Qtrpl outskirts of Baghdad.

Only a few details of al-Khwārizmī’s life can be gleaned from the brief notices in Islamic bibliographical works and occasional remarks by Islamic historians and geographers. The epithet “al-Khwārizmī” would normally indicate that he came from Khwārizm (Khorezm, corresponding to the modern Khiva and the district surrounding it, south of the Aral Sea
in central Asia). But the historian al-Tabarī gives him the additional epithet
“al-Qutrubbullī,” indicating that he came from Qutrubbull, a district between the Tigris and Euphrates not far from Baghdad,1 so perhaps his ancestors, rather than he himself, came from Khwārizm;
All that can be said concerning the date and order of composition of al-Khwārizmī’s works is the following. The Algebra and the astronomical work, as we have seen, were composed under al-Ma’mũn, in the earlier part of al-Khwārizmī’s career. The treatise on Hindu numerals was composed after the Algebra, to which it refers. The treatise on the Jewish calendar is dated by an internal calculation to 823-824. The Geography has been tentatively dated by Nallino (“al-Khuwārizmī,” p. 487) to soon after 816-817, since one of the localities it mentions is Qiman, an Egyptian village of no importance whatever except that a battle was fought there in that year; but the inference is far from secure. The Chronicle was composed after 826, since al-Tabarī quotes it as an authority for an event in that year.5
