Which Islamic scholar is associated with the development of algebra during the Islamic Golden Age?

• A. Ibn Sina
• B. Al-Khwarizmi
• C. Ibn al-Haytham
• D. Omar Khayyam

Answer: (B)

Algebra as a formal method emerged during the Islamic Golden Age largely due to a Persian scholar at the Abbasid court who wrote a foundational treatise introducing general procedures for reducing and balancing equations and solving for unknowns. The book’s title centers on al-jabr, the operation of restoring or completing the square, and from this term the word algebra itself is derived. This work presented systematic, step-by-step methods that could be applied to any linear or quadratic equation, marking a shift from geometric tricks to general techniques that could be reused across many problems. Its influence extended beyond the Islamic world and into Europe, helping to shape the development of algebra for centuries. Other prominent figures of the era contributed in different areas or advanced mathematics in other ways—Omar Khayyam, for instance, worked on solving certain equations geometrically—but the association with laying down the general foundations of algebra points most directly to Al-Khwarizmi.
