In mathematics, a monomial is, roughly speaking, a polynomial [Polynomial] which has only one term. Two definitions of a monomial may be encountered:

  1. A monomial, also called power product, is a product of powers of variables with nonnegative integer exponents, or, in other words, a product of variables, possibly with repetitions. For example, \(x^{2}yz^{3}\) is a monomial.
  2. A monomial is a monomial in the first sense multiplied by a nonzero constant, called the coefficient of the monomial.
