Biography of Al-KhwarizmiAbu Abdallah Muhammad ibn Musa al-Khwarizmi (Latinized to Algoritmi) was a Persian mathematician, astronomer and geographer. He is largely responsible for introducing the number system we now use to the Western world, relying on the Hindu-Arabic numerals (0 - 9) and a place value system. His book, The Compendious Book on Calculation by Completion and Balancing, shows the beginnings of algebra, and provides an account of how to solve linear and quadratic equations.

"The Compendious Book on Calculation by Completion and Balancing"Al-Khwarizmi's book gave a systemic account of how to solve linear and quadratic equations.
Although he used words instead of letters, his method of solving the equations led to algebra. The slider below discusses his methods.
