Why two negatives is a positive?

I feel that two negatives are positive because you add* your two negative integers* together, you would be doing this: -+- (negative + negative) so the response is, is that if two integers where both negative, you would add, just like if there were two positives, you would add, but not if you have different signs. (positive+negative) you would subtract. Just as the same with negative + positive. [REVIEW: if the sign is the same, add, if the sign is different, you subtract.] *=you may not always add *=integers- a fancy word for numbers.
