A monomial is a number, variable, or product of numbers and variables, like 2, m, 2xy, or -5x^2 . Something would not be a monomial if it has a plus or minus sign, a variable in the bottom of a fraction, a negatiave exponent on a variable, or something with a square root. A polynomial is the sum or difference of monomials. Each monomial piece is a term. The degree of a polynomial is the highest exponent on the variable. The math instructions "evaluate" are like substitute- they mean replace the variables with the given numbers and simplify.
