This applies to both multiplication and division. The rules of signs tell us that when we multiply or divide two numbers with the same sign, the result is positive. On the other hand, when we multiply or divide two numbers with different signs, the result will be negative. Some prefer to say that plus times plus is plus, or that minus times minus is plus, but I prefer to explain it another way. That's all for this lesson. I invite you to take on the challenge and become a member of this channel.
