What is the Degree of a Monomial - Algebra I

The degree of a monomial is the sum of the exponents of its variables. The degree of a non-zero constant is 0. Zero has no degree.

A monomial is a real number, a variable, or a product of a real number and one or more variables with whole-number exponents.

Examples:
5x has a degree of 1. 5x = 5x^1 so the exponent is 1
6x^2y^3 has a degree of 5. The exponents are 2 and 3. Their sum is 5.
4 has a degree of 0. 4 = 4x^0. The degree of a nonzero constant is zero.
