Mohammed Ben Musa (Abu Abdullah Mohammad Ibn Musa al-Khawarizmi) (c. 790-840) - mathematician, astronomer and geographer - is generally considered the "Father of Algebra." Not only did he initiate the subject of algebra in a systematic form but he also developed it to the extent of giving analytical solutions of linear and quadratic equations, which established him as the founder of Algebra. The name algebra was derived from his famous book Al-Jabrwa-al-Muqabilah. His arithmetic synthesized Greek and Hindu knowledge and also contained his own contribution of fundamental importance to mathematics and science. He explained the use of zero, a numeral of fundamental importance developed by the Arabs; he developed the decimal system so that the overall system of numerals, algorithm is named after him. In addition to introducing the Indian system of numerals (now generally known as Arabic numerals), he developed at length several arithmetical procedures, including operations on fractions. It
