Multiplying positive and negative numbers may seem confusing. However, in this math tutorial, multiplying numbers with different or same signs is made easy and eliminates all confusion. The narrator of the video explains the key rules to remember when dealing with the possible combination of positive and negative numbers. The video breaks it down to two key rules. When you have a negative and a positive number; the result will always be negative. When you are given two numbers that have the same sign (both positive or both negative) then the result will be positive. With these easy to remember rules and the helpful illustrations in the video, multiplying positive and negative numbers will no longer be a worry.
