This lesson goes through some example problems from a practice Algebra exam. Each step in the problems is shown clearly. The first problem is started and then skipped over quickly without any explanation, however. The topics covered in this video are multiplying, dividing, adding, subtracting, factoring, simplifying, and canceling fractions with polynomials.
