Each number has an “additive inverse” associated to it (a sort of “opposite” number), which when added to the original number gives zero. … The fact that the product of two negatives is a positive is therefore related to the fact that the inverse of the inverse of a positive number is that positive number back again.

How is a negative times a negative a positive?

We can represent “removes” by a negative number and figure out the answer by multiplying. This is an illustration of a negative times a negative resulting in a positive. If one thinks of multiplication as grouping, then we have made a positive group by taking away a negative number twelve times.

What is a negative times a positive?

What is negative I equal to?

“I” squared is the same thing as the square root of negative 1 times the square root of negative one. (This is, again, because “I” is equal to the square root of negative 1) Since we know that square rooting and squaring are opposites, the two will cancel each other out, leaving you with negative 1.
