Several examples of different types of algebraic expressions are multiplied. The distributive property demonstrates the steps needed to multiply the terms in the expressions. Sal combines the like-terms at the end of the presentation....

Adding two polynomials begins with simplifying when possible. Sal demonstrates the process he uses to combine like terms and explains why the process works. This video would be great for those who need a quick refresher.

The foil method had been used for years as a way to remember how to simplify complex numbers. This process is demonstrated step-by-step, slowly so the learner will be able to follow along as the instructor solves the problem. Intended...
