This article is about the branch of mathematics; for other uses of the term see algebra (disambiguation).
Algebra (from Arabic: الجبر, al-ğabr) is a branch of mathematics concerning the study of structure, relation and quantity. Elementary algebra is often taught in secondary education and gives an introduction to the basic ideas of algebra: studying what happens when numbers are added or multiplied, and how to make polynomials and find their roots.

Algebra is much broader than elementary algebra and can be generalized. Rather than working directly with numbers, one can work with symbols, variables, or elements of some set. Addition and multiplication are viewed as general operations, and their precise definitions lead to structures such as groups, rings and fields.

Together with geometry and analysis, algebra is one of the three main branches of mathematics.
