The 9th century mathematician Muhammad Ibn Musa-al-Kharazmi created the Logarithm table, developed algebra and expanded upon Persian and Indian arithmetic systems. His writings were translated into Latin by Gerard of Cremona under the title: De jebra et almucabola. Robert of Chester also translated it under the title Liber algebras et almucabala. The works of Kharazmi “exercised a profound influence on the development of mathematical thought in the medieval West”.
