DEGREE

• The degree of a monomial is determined by adding
  the exponents of its variables.
• So, to find the degree of a POLYnomial, find the
  degree of each separate MONOmial. The Monomial
  with the HIGHEST sum determines the degree of the
  problem.

Ascending Descending Order

• Ascending means to count up!
• So, order the VARIABLES exponents from
  least to greatest.
• Descending means to count down!
• So, order the VARIABLES exponents from
  greatest to least.
