Degree of a Monomial
The degree of a monomial is the sum of the exponents of all its variables.
Example 1:
The degree of the monomial 7y3z2 is 5 (= 3 + 2).
Example 2:
The degree of the monomial 7x is 1 (since the power of x is 1).
Example 3:
The degree of the monomial 66 is 0 (constants have degree 0).
