Latinized versions of his name and of his most famous book title live on in the terms algorithm and algebra. In fact, the words algorithm and algebra come from his name and the title of one of his works, respectively. He wrote a book on algebra from whose title the word algebra is derived, and he wrote a book on calculation that introduced to Europe the Hindu-Arabic numerals and how to do arithmetic with them. His mathematical books introduced the ideas of algebra and Hindu-Arabic numerals to Western mathematicians during the Middle Ages.

List and Biographies of Great Mathematicians Al Khwarizmi Al Khwarizmi was a nineteenth century eminent and multi-faceted Persian mathematician, geographer and astronomer. In the House of Wisdom of Baghdad he was a scholar.

His works was brought to Western World through Latin translation that had been conducted in the 12th century. The work on Arabic numerals highlights the decimal positional number system. Moreover, the first systematic solution of linear and quadratic equations was presented in his book The Compendious Book on Calculation by Completion and Balancing. For his astounding amount of influential work in mathematics especially, he is deemed the father of algebra. Besides mathematics, he left his imprints on the field of astronomy and astrology as well.

He was an orthodox Muslim, a firm believer in Islamic way of life. Ibn al-Nadim wrote a biography on Al Khwarizmi which mainly included the books that he wrote. Most of his achievements dated back to the years to Baghdad had become the center of learning and hub of all scientific studies, subsequent to the Muslim conquest of Persia.

A great number of traders, merchants and seekers of knowledge traveled to Baghdad from around the world including Al Khwarizmi. There he studied books on mathematics and science. Additionally, he studied the translation of Sanskrit and Greek manuscripts on scientific research.

The solution to quadratic and linear equation was an essential step in the derivation of the algebraic field. Around c. He was also familiar with classic Greek mathematician. It improved upon the data given in the book and enhanced the features of Africa, Asia and Mediterranean Sea.

Moreover, he is accredited for advancement in European mathematics by means of his contribution through books which were subsequently translated into Italian. He also made mechanical devices and gadgets like sundial and astrolabe the subject of his books.

The Italian translation of his book was conducted by Robert of Chester as Liber algebrae et almucabala. That is how the word algebra was coined which was inspired by the Arabic word al-jabr.

The book dealt with detailed account of the fundamental methods of reduction and balancing and solving polynomial equations. Famous Mathematicians.

## Al Khwarizmi

He is also the inventor of many mathematical methods and a branch of math, called Algebra. Furthermore, he was the first to use decimals to express the fractions. The exact date of his birth is not clear, but it is normally considered to be There is very little information about his early life, but it is clear that he was one of the brilliant students in Baghdad, Iraq. Baghdad was the city of knowledge at the time of the Golden Era of Muslims. Al-Khwarizmi was one of the many researchers working in the House of Wisdom as mathematician, geologist, and astronomer.

## Al-Khwārizmī

Robertson wrote in the MacTutor History of Mathematics archive : Perhaps one of the most significant advances made by Arabic mathematics began at this time with the work of al-Khwarizmi, namely the beginnings of algebra. It is important to understand just how significant this new idea was. It was a revolutionary move away from the Greek concept of mathematics which was essentially geometry. Algebra was a unifying theory which allowed rational numbers , irrational numbers , geometrical magnitudes, etc. It gave mathematics a whole new development path so much broader in concept to that which had existed before, and provided a vehicle for future development of the subject. 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. It no longer concerns a series of problems to be solved , but an exposition which starts with primitive terms in which the combinations must give all possible prototypes for equations, which henceforward explicitly constitute the true object of study.
