Abu Kamil

From Wikipedia, the free encyclopedia

Abu Kamil Shuja ibn Aslam ibn Muhammad ibn Shuja (c.850–930), or just Abu Kamil (Arabic: ابو كامل) for short, was a mathematician who lived in Egypt during the Islamic Golden Age. He has also been called al-Hasib al-Misri—literally, "the Egyptian calculator."

Unlike the many polymaths of this era—notably al-Khwarizmi, al-Kindi, Ibn Sina (Avicenna in the West), and Ibn Rushd (Averroes)—Abu Kamil was a specialist. His field was algebra. His Book on rare things in the art of calculation treated systems of equations whose solutions are whole numbers or fractions and also combinatorics. This work led to later research into the real numbers, solutions of polynomials, and finding roots by later scientists of the age such as al-Karaji and as-Samaw'al.
