Expressions that are products of numbers, variables, and their degrees are called monomials. Expressions that are sums or differences of two or more monomials are called polynomials. A polynomial where there are no similar monomials, is called the polynomial in standard form. A degree of a monomial is the sum of powers of its variables. Degree of is 2+3=5. A degree of a polynomial is the maximum degree of its monomials. Degree of is 4. When submitting questions to tutors, use the caret symbol ^ to denote powers. x^2 means x squared.
