- variables
- only addition, multiplication and exponentiation to positive integer powers
- a finite number of terms
a polynomial with one term is a monomial
a polynomial with two terms is a binomial
a polynomial with three terms is a trinomial
thankfully polynomials with more than three terms don’t have special names
