by al-Khwarizmi
The Algebra of Mohammed Ben Musa is a translation of al-Khwarizmi’s groundbreaking mathematical treatise, Kitab al-Jabr wa-l-Muqabala. Written in Baghdad around 205 AH (820 CE) under the patronage of Caliph al-Ma'mun, the work introduced systematic methods for solving linear and quadratic equations. It is the origin of the term "algebra" (from "al-jabr") and emphasizes practical applications through numerous examples related to inheritance, commerce, and land surveying. Synthesizing mathematical knowledge from Indian, Persian, and Greek traditions, this treatise laid the foundations for a distinctively Islamic science. Its Latin translation in the 12th century had a profound impact on the development of European mathematics.
