Who invented algebra and why?
The word "algebra" comes from the Arabic word "al-jabr", meaning reunion and is part of the title of from a book on mathematics written by Muhammed ibn Musa Al-Khwarizmi.
He was an Arab mathematician who worked on algebra, arithmetic, and astronomical tables. The word "algorithm" is also derived from his name.
Al-Khwarizmi did not invent algebra but his book was very influential in bringing algebra to the western world so he is generally considered the father of algebra.
A Greek mathematicians Diophantus is sometimes called the father of algebra as he developed one of the earliest forms of solving equations. However he used mostly special ad hoc methods to solve equations, whilst Al- Khwarizmi was the first to solve equations using general methods.
Algebra is a tremendously useful mathematical tool, without which modern science and technology would not have been possible. Algebra was invented as a tool for solving mathematical problems, and it has proved to be tremendously useful. Modern technology as we know it would have been impossible without the use of algebra. +++ More accurately, algebra is the set of symbols and rules used to construct mathematics. It is not a calculating tool to solve problems…
Algebra was invented by the Muslim mathematician Al-Khwarizmi in the book he wrote in 820. Algebra is the Arabic word (aljabr) for "equation", and the word "algorithm" comes from the author's name, Al-Khwarizmi. He is rightly known as "the father of Algebra". -J. J. O'Conner and E. F.
