The early Arab mathematician and astronomer al-Khwarizmi has been considered by some to be the founder of algebra, a branch of mathematics dealing with equations containing unknown quantities and variables. While this has been disputed, it is certain that his publications on the subject were among the earliest available to the Arab world, and were highly influential among later audiences. (Sen, 2)
One of the most well-known early Arab scientists, he wrote his famous treatise, "The Compendious Book on Calculation by Completion and Balancing," by the year 830. Later, this work had a great impact on Western mathematics and science; Latin translations of his work were quite important to scholars and businesspeople during the Middle Ages. Al-Khwarizmi is also known for bringing the Hindu system of fixed numerals to international attention. He wrote an Arab-language text that explained Hindu methods of calculation, which depended upon written numerals rather than the more primitive counting techniques that were widely used at the time.
The 'publication' of the book of al-Khwarizmi at the beginning of the ninth century-between 813 and 833 -is an outstanding event in the history of mathematics. For the first time, one could see the term algebra appearing in a title to designate a distinct mathematical discipline, equipped with a proper technical vocabulary. ...
