Outline of algebra

Algebra is one of the main branches of mathematics, covering the study of structure, relation and quantity. Algebra studies the effects of adding and multiplying numbers, variables, and polynomials, along with their factorization and determining their roots. In addition to working directly with numbers, algebra also covers symbols, variables, and set elements. Addition and multiplication are general operations, but their precise definitions lead to structures such as groups, rings, and fields.

Algebraic equations
See also: Equation

An algebraic equation is an equation involving only algebraic expressions in the unknowns. These are further classified by degree.

Linear equation – algebraic equation of degree one.
Polynomial equation – equation in which a polynomial is set equal to another polynomial.
Transcendental equation – equation involving a transcendental function of one of its variables.
Functional equation – equation in which the unknowns are functions rather than simple quantities.
Differential equation – equation involving derivatives.
Integral equation – equation involving integrals.
Diophantine equation – equation where the unknowns are required to be integers.

Algebra –
Fundamental theorem of algebra – states that every non-constant single-variable polynomial with complex coefficients has at least one complex root. This includes polynomials with real coefficients, since every real number is a complex number with an imaginary part equal to zero.
Linear equation – an algebraic equation with a degree of one
Quadratic equation – an algebraic equation with a degree of two
Cubic equation – an algebraic equation with a degree of three
Quartic equation – an algebraic equation with a degree of four
Quintic equation – an algebraic equation with a degree of five
