A polynomial is a term or a finite sum of terms in which all variables have whole number exponents and no variables appear in the denominator. In this lesson we are going to learn how to add and subtract polynomials. Polynomials are classified by how many terms they have, and the largest power present. To evaluate a polynomial we substitute a value into all variables, and then simplify. To add or subtract polynomials together, we add or subtract the like terms of each of them. When adding or subtracting, it is often helpful to line up the like terms.
