Does a negative plus a negative equal a negative?

Negative plus Negative would equal positive in Maths. like this: -7 + -8 = 1 Because you're adding a minus It Will Not Equal a Positive it will Equal a Negative. -7+-8= -15. Because you are adding a negative to another negative. If the problem was -7+8= 1. Because you are taking seven out of that eight. If It were to be multiplication than a negative TIMES a negative would have been a positive(-8 x -7=56). And a negative TIMES a positive would be a negative (-8 x 7=-56).
