In mathematics, a polynomial is an expression of finite length constructed from variables (also called indeterminates) and constants, using only the operations of addition, subtraction, multiplication, and non-negative integer exponents. However, the division by a constant is allowed, because the multiplicative inverse of a non-zero constant is also a constant. For example,  is a polynomial, but  is not, because its second term involves division by the variable  ( ), and also because its third term contains an exponent that is not a non-negative integer ( ).
