In this lesson I will teach you how to add and subtract polynomials. You want to make sure you remember how to add/subtract like terms- you may want to review the topic in the real numbers chapter. If you have an excellent grasp on like terms then this lesson will not be too difficult. Students seem to make more mistakes with subtracting polynomials because you have to change signs so be careful. Also, you need to practice this skill way beyond a few problems. The worst thing you can do is watch the lesson, say “I get it” and move on without practice- remember, in math there are no short cuts for truly mastering the subject.
