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.
