"Al-Kitab al-Mukhtasar fi Hisab al-Jabr wal-Muqabala" is a foundational mathematical text written by the Persian mathematician Muhammad ibn Musa al-Khwarizmi in the 9th century. The title translates to "The Compendious Book on Calculation by Completion and Balancing," and it systematically presents the principles of algebra. This work is significant for introducing systematic methods for solving linear and quadratic equations. Al-Khwarizmi's approach laid the groundwork for modern algebra, influencing both Islamic mathematics and European mathematical thought during the Renaissance.
