What is al-Khwārizmī famous for? Al-Khwārizmī is famous for his mathematical works, which introduced Hindu-Arabic numerals and algebra to European mathematicians. In fact, the words algorithm and algebra come from his name and the title of one of his works, respectively.
Muhammad al-Khwarizmi developed the concept of algebra by generating a new method for solving linear and quadratic equations. His revolutionary technique began by putting the equations in one of six standard forms where b and c were both positive integers.
Muhammad ibn Musa al-Khwarizmi was a 9th-century Muslim mathematician and astronomer. He is known as the “father of algebra”, a word derived from the title of his book, Kitab al-Jabr. His pioneering work offered practical answers for land distribution, rules on inheritance and distributing salaries.
Al-Khwārizmī is also said to have developed the lattice, or sieve, multiplication method of multiplying large numbers. His lattice method was introduced into Europe by Italian mathematician Fibonacci, which helped spread his work in the West.
It is safe to say that big mathematicians such as Leonardo Fibonacci (1175-1230), Alberd (1196- 1280), and Roger Bacon (1214-1294) used Al Khwarizmi's algorithms and solutions in their studies. This influence clearly appears in Practica Geometria written by Leonardo Fibonacci.
Kalif al-MamunAl-Khwarizmi was one of the learned men who worked in the House of Wisdom. Al-Khwarizmi flourished while working as a member of the House of Wisdom in Baghdad under the leadership of Kalif al-Mamun, the son of the Khalif Harun al-Rashid, who was made famous in the Arabian Nights.
Notes: Algebra was invented by Aryabhatta, who was a pioneer in astrology, astronomy and Mathematics. He viewed Mathematics as a different subject in itself. However, most people consider Muhammad ibn Musa al-Khwarizmi as father of Algebra now.

Brahmagupta"Zero and its operation are first defined by [Hindu astronomer and mathematician] Brahmagupta in 628," said Gobets. He developed a symbol for zero: a dot underneath numbers.
Al-Khwarizmi wrote a major work on geography which give latitudes and longitudes for 2402 localities as a basis for a world map. The book, which is based on Ptolemy's Geography, lists with latitudes and longitudes, cities, mountains, seas, islands, geographical regions, and rivers.
