Degree of a polynomial

(重定向自Total degree)

The degree of a polynomial is the highest degree of its terms when the polynomial is expressed in its canonical form consisting of a linear combination of monomials. The degree of a term is the sum of the exponents of the variables that appear in it. The term order has been used as a synonym of degree but, nowadays, may refer to several other concepts (see order of a polynomial). For example, the polynomial 7x^2y^3 + 4x - 9 has three terms. (Notice, this polynomial can also be expressed as 7x^2y^3 + 4x^1y^0 - 9x^0y^0.) The first term has a degree of 5 (the sum of the powers 2 and 3), the second term has a degree of 1, and the last term has a degree of 0. Therefore, the polynomial has a degree of 5 which is the highest degree of any term.
