Averroes Ibn Rushd (Arabic: ‎ ‎ ; 14 April 1126 – 10 December 1198), full name (Arabic: أبو الوليد محمد ابن احمد ابن رشد‎ , "ʾAbū l-Walīd Muḥammad Ibn ʾAḥmad Ibn Rushd " ‎ ), often Latinized as Averroes ( ), was a medieval Andalusian polymath. He wrote on logic, Aristotelian and Islamic philosophy, theology, the Maliki school of Islamic jurisprudence, psychology, political and Andalusian classical music theory, geography, mathematics, and the mediæval sciences of medicine, astronomy, physics, and celestial mechanics. Ibn Rushd was born in Córdoba, Al Andalus (present-day Spain), and died at Marrakesh in present-day Morocco. His body was interred in his family tomb at Córdoba. The 13th-century philosophical movement in Latin Christian and Jewish tradition based on Ibn Rushd's work is called Averroism.
Mathematics in medieval Islam Mathematics during the Golden Age of Islam, especially during the 9th and 10th centuries, was built on Greek mathematics (Euclid, Archimedes, Apollonius) and Indian mathematics (Aryabhata, Brahmagupta). Important progress was made, such as the full development of the decimal place-value system to include decimal fractions, the first systematised study of algebra (named for "The Compendious Book on Calculation by Completion and Balancing" by scholar Al-Khwarizmi), and advances in geometry and trigonometry.
