Student Outcomes

Students understand that the sum or difference of two polynomials produces another polynomial and relate polynomials to the system of integers; students add and subtract polynomials.

Lesson Summary

A **monomial** is a polynomial expression generated using only the multiplication operator (__×__). Thus, it does not contain + or – operators. Monomials are written with numerical factors multiplied together and variable or other symbols each occurring one time (using exponents to condense multiple instances of the same variable)

A **polynomial** is the sum (or difference) of monomials.

The **degree of a monomial** is the sum of the exponents of the variable symbols that appear in the monomial.

The **degree of a polynomial** is the degree of the monomial term with the highest degree.
