The **degree of a** monomial is the sum of the exponents of all its variables.

**Example 1:**

The degree of the monomial 7*y*^{3}*z*^{2} is 5 (= 3 + 2).

**Example 2:**

The degree of the monomial 7*x* is 1 (since the power of *x* is 1).

**Example 3:**

The degree of the monomial 66 is 0 (constants have degree 0).
