What do 2 positives make?
Example×two positives make a positive:3 × 2 = 6×two negatives make a positive:(−3) × (−2) = 6×a negative and a positive make a negative:(−3) × 2 = −6×a positive and a negative make a negative:3 × (−2) = −6
What is a negative and a 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.

Is sum always positive?
1 Expert Answer That depends on their absolute values. If the negative number has a greater absolute value than the absolute value of the positive number, the sum will be negative. If the positive number has a greater absolute value than the absolute value of the negative number, the sum will be positive.
Why is the sum of two negative numbers negative?
