I have always heard that multiplication is fast adding of the same number. This made sense until we got to negative numbers. Why would two negative numbers become a positive number when they are multiplied if it is indeed just adding the same number? I have asked several people this and never got a straight answer. Please help me!
In: Mathematics
Multiplication being repeated addition isn’t the definition of multiplication, it’s just a metaphor to explain its function. That metaphor doesn’t work when referring to the product of two negative numbers.
