The rules for multiplying signed numbers may be formulated from the fact that multiplication serves as a shorthand notation for addition. For example, 4 x (−3), which means "4 times negative −3" is the same as the following: (-3) + (-3) + (-3) + (-3) = -12 Therefore, it follows that multiplication of a negative and positive number represents addition of negative numbers.
