Algoritmi de numero Indorum, the Latin translation of his other major work on the Indian numerals, introduced the positional number system and the number zero. “The Arabic text is lost but a Latin translation, Algoritmi de numero Indorum (in English Al-Khwarizmi on the Hindu Art of Reckoning) gave rise to the word. Another arithmetic of Al-Khowarizmi was translated into Liber Algorismi de numero Indorum (the book of Al-Khowarizmi) giving rise to the word algorithm.

In the 12th century, Latin translations of his textbook on arithmetic Algorithmo de Numero Indorum which codified the various Indian numeralsintroduced the decimal positional number system to the Western world.

Brill, Leiden, the Netherlands. Another important aspect of the introduction of algebraic ideas was that it allowed mathematics to be applied to itself in a way which had not happened before. His solutions were accompanied by geometric demonstrations. In a sense, al-Khwarizmi is more entitled to be called “the father of algebra” than Diophantus because al-Khwarizmi is the first to teach algebra in an elementary form and for its own sake, Diophantus is primarily concerned with the theory of numbers.

Byzantine mathematics European mathematics Indian mathematics. A History of Mathematicsp. He assisted a project to determine the circumference of the Earth and in making a world map for al-Ma’munthe caliph, overseeing 70 geographers. It is quite unlikely that al-Khwarizmi knew of the work of Diophantus, but he must have been familiar with at least the astronomical and computational portions of Brahmagupta; yet neither al-Khwarizmi nor other Arabic scholars made use of syncopation or of negative numbers.

Analysis of the Equation of Time. Algebra is a compilation of rules, together with demonstrations, for finding solutions of linear and quadratic equations based on intuitive geometric arguments, rather than the abstract notation now associated with the subject.
