The Egyptian calculator who basically came from Egypt and activated after Al-Khwarizmi, who died c. 930, and before Al-'Imrani, who died in 955, and therefore can be placed about the beginning of the tenth century. He was a mathematician who perfected Al-Khwarizmi's work on algebra and whose mathematics included a number of topics like determination and construction of both roots of quadratic equations; multiplication and division of algebraic quantities; addition and subtraction of radicals; study of the pentagon and decagon (algebraic treatment). His (Book on algebra) is available in many manuscripts, like in Istanbul and Berlin, and in addition in diverse languages and translations like Hebrew, German, and English. Abu Kamil wrote (Rarities of arithmetic) which is available, but incomplete at Leiden (199/6), but there are more complete Latin translations of this treatise in Paris (7377 a/6), and Hebrew translations from Spanish. His treatise on the measurement of the pentagon and Decagon, in Arabic Misahat Al-Mukhamas wa'l muashar, is available in Istanbul (Kara Mustafa 379/2) and in Latin translation in Paris (7377 a/5) and in translation into Hebrew, German, Italian, and partial translation into Russian. Abu Kamil also wrote on inheritance by means of roots, inheritance by means of Algebra, a book on indefinite problems, a treatise on the measurement of the land, another on measurement and geometry, one on reunion and separation and another entitled (Sufficient Book). Abu Kamil's mathematics were widely used by his successors whether Muslims or Western Christians, like Al-Karkhi and Leonardo da Pisa. There have been a number of modern studies of Abu Kamil including those by Weinbergand Levey.
