In this lesson you'll learn how to multiply and divide signed numbers. To summarize, multiplying same signs gives a positive answer. Multiplying opposite signs gives a negative answer. The numbers themselves don't matter. Just multiply them and then determine the sign of your answer based on these three rules. These rules are exactly the same for division. Just remember that they are the same.
