Algebraic equations
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 only solutions of interest of the unknowns are the integer ones.

History of algebra
General algebra concepts 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. Equations – equality of two mathematical expressions 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 Polynomial – an algebraic expression consisting of variables and coefficients Inequalities – a comparison between values Functions – mapping that associates a single output value with each input value Sequences – ordered list of elements either finite or infinite Systems of equations – finite set of equations Vectors – element of a vector space Matrix – two dimensional array of numbers Vector space – basic algebraic structure of linear algebra Field – algebraic structure with addition, multiplication and division Groups – algebraic structure with a single binary operation Rings – algebraic structure with addition and multiplication
