+(+) Two like signs become a positive sign 3+(+2) = 3 + 2 = 5
−(−) 6−(−3) = 6 + 3 = 9
+(−) Two unlike signs become a negative sign 7+(−2) = 7 − 2 = 5
−(+) 8−(+2) = 8 − 2 = 6

## What are the rules for negative and positive numbers?

The rules for multiplication and division are simple: If both numbers are positive, the result is positive. If both numbers are negative, the result is positive. (Basically, the two negative values cancel each other out).

## Why are two negatives multiplied positive?

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.
