An algebraic expression that is a single term of a polynomial; monomials are constants or the product of a constant and one or more variables raised to whole-number powers. The letter used to represent the set of natural numbers or counting numbers.
In mathematics, a monomial (or mononomial) is a particular kind of polynomial, having just one term. Given a natural number n and a variable x, the power function defined by the rule f(x)=xn is therefore a monomial. Given several unknown variables (say, x, y, z) and corresponding natural number exponents (say, a, b, c), the product of the resulting univariate monomials is also a monomial (e.g., the function determined by the rule f(x)=xaybzc).
