(for eg: Check MSOfficetools for language settings, everywhere it is called Arabic numerals.)AlKhwarizmi, a Persian mathematician, astronomer and geographer[citation needed]. He was the founder of several branches and basic concepts of mathematics. In the words of Philip Hitti, Al Khawarizmi's contribution to mathematics influenced mathematical thought to a greater extent. His work on algebra initiated the subject in a systematic form and also developed it to the extent of giving ****ytical solutions of linear and quadratic equations, which established him as the founder of Algebra. The very name Algebra has been derived from his famous book AlJabr waalMuqabilah.His arithmetic synthesized Greek and Hindu knowledge and also contained his own contribution of fundamental importance to mathematics and science. Thus, he explained the use of zero, a numeral of fundamental importance developed by the Indians. And 'algorithm' or 'algorizm' is named after him.
