 Equations can be classified according to the types of operations and quantities involved. Important types include:An algebraic equation or polynomial equation is an equation in which both sides are polynomials (see also system of polynomial equations). These are further classified by degree:linear equation for degree onequadratic equation for degree twocubic equation for degree threequartic equation for degree fourquintic equation for degree fiveA Diophantine equation is an equation where the unknowns are required to be integersA transcendental equation is an equation involving a transcendental function of its unknownsA parametric equation is an equation for which the solutions are sought as functions of some other variables, called parameters appearing in the equationsA functional equation is an equation in which the unknowns are functions rather than simple quantitiesA differential equation is a functional equation involving derivatives of the unknown functionsAn integral equation is a functional equation involving the antiderivatives of the unknown functionsAn integro-differential equation is a functional equation involving both the derivatives and the antiderivatives of the unknown functionsA difference equation is an equation where the unknown is a function f which occurs in the equation through f(x), f(x−1), …, f(x−k), for some whole integer k called the order of the equation. If x is restricted to be an integer, a difference equation is the same as a recurrence relation
