Al-jabr

Definition

Al-jabr is an Arabic term meaning 'the reunion of broken parts' and refers specifically to the mathematical discipline of algebra. This concept originated in the works of the mathematician Al-Khwarizmi in the 9th century, where it provided systematic methods for solving linear and quadratic equations. Al-jabr laid the foundation for modern algebra and greatly influenced mathematical education and practices in Islamic culture and beyond.
