Al-Jabr

Al-Jabr, meaning "completion" or "rejoining," is a foundational concept in algebra that involves systematically solving equations to find unknown values. It originated from the Arabic mathematician Al-Khwarizmi's work in the 9th century, who developed methods to balance and manipulate equations by performing operations such as addition, subtraction, multiplication, and division. These techniques allow for the replacement of unknowns with known quantities, making complex problems more manageable. Today, algebra provides a framework for solving various real-world problems across science, engineering, finance, and technology by abstracting and generalizing arithmetic procedures.
