Abu Jaafar Mohammad Ibn Mousa Al Khwarizmi was a arab mathematician who helped to perfect algebra. He was born in Uzbekistan around 780 AD. His parents settled in Baghdad where he eventually became a sunni muslim. He was invited to the house of wisdom in Baghdad where he translated many Greek philosophical and scientific works eventually going into the study of geometry and astronomy. His most significant contribution was the “Hisab Al jabr Wal-Muqabalah” because it defined the study of algebra. It provided many simple quadratic equations. It dealt with solving practical computational problems so it was limited to the first and second degrees. Al Khwarizimi also wrote a treatise on Hindu-Arabic numerals, it was called the “Algoritmi de numero indorum” in latin. It described the Hindu place value system using the numerals 1,2,3,4,5,6,7,8,9 and 0. This work was responsible for introductimg arabic numerals and the 0 symbol to the west.
