Can the sum of two negative numbers be positive?
Rule: The sum of any integer and its opposite is equal to zero. Summary: Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.

Why is minus a minus a plus?
This is in fact the reason why the negative numbers were introduced: so that each positive number would have an additive inverse. 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.
