Al-Khwarizmi

Al-Khwarizmi, a 9th-century Persian mathematician, is known as the "Father of Algebra." His book "Kitab al-Jabr wa al-Muqabala" introduced systematic methods for solving equations and laid the foundation for algebra. He also made contributions to trigonometry and the adoption of Arabic numerals, shaping the development of mathematics.

The term algorithm is derived from the algorism, the technique of performing arithmetic with Hindu–Arabic numerals popularised by al-Khwarizmi in his book On the Calculation with Hindu Numerals.

Muhammad ibn Musa al-Khwarizmi, or simply al-Khwarizmi was a mathematician active during the Islamic Golden Age, who produced Arabic-language works in mathematics, astronomy, and geography. Around 820, he worked at the House of Wisdom in Baghdad, the contemporary capital city of the Abbasid Caliphate. One of the most prominent scholars of the period, his works were widely influential on later authors, both in the Islamic world and Europe.

• His popularizing treatise on algebra, compiled between 813 and 833 as Al-Jabr (The Compendious Book on Calculation by Completion and Balancing), presented the first systematic solution of linear and quadratic equations.
