Multiplying Integers and Their Properties

This video tutorial teaches how to multiply integers using patterns. It begins with a review of multiplication tables and demonstrates how patterns can help in understanding multiplication rules. The lesson covers the rules for multiplying integers: positive times positive equals positive, positive times negative equals negative, and negative times negative equals positive. The commutative property is also discussed, emphasizing that the order of multiplication does not affect the result. The tutorial concludes with a summary of these rules, reinforcing the concept that the sign of the product depends on the signs of the factors.
