The Algebra of Mohammed Ben Musa

Published in 1831. Abu Abdallah Mohammed Ben Musa, of Khowarezm, who it appears, from his preface, wrote this Treatise at the command of the Caliph Al Mamun, was for a long time considered as the original inventor of Algebra. That he was not the inventor of the Art, is now well established, but that he was the first Mohammedan who wrote upon it, is to be found asserted in several Oriental writers. He was also the first Mussulman who had ever written on the solution of problems by the rules of completion and reduction.
