Question

-5+(-3).I know the answer is -8 but how because a negative plus a negative is a positive.

Answer 1

“two negatives = positive” rule works for multiplication and division.

Explanation:

-5 + (-3) example

imagine a number line with 0 in the center. From (0) You move left 5 places to (-5) on the number line. Now you move another 3 more to the left (-3) and land on (-8).

You are combining the negatives. I hope this helps.
