Standard form of a polynomial with multiple variables

What is standard form for polynomials with multiple variables?

Standard form of polynomials with multiple variables

A polynomial with multiple variables is in standard form if:

1. it does not contain like terms (monomials);
2. the polynomial terms (monomials) are written by descending degree.

Examples of standard form of polynomials with multiple variables:

7a + 5b + 3c
7a2 + 2b - c
7a4b3 + 2b2 + 5c + 6
7a5b4 + 2c3d2 - 12x2
17a15b4 + 12a11b2 + 2a2b + c + 352
