Why does adding two negatives make 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.
Do you add or subtract when you have 2 negatives?
Rule 3: Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign.

What cancels each other out in math?
Cancelling out is a mathematical process used for removing subexpressions from a mathematical expression, when this removal does not change the meaning or the value of the expression because the subexpressions have equal and opposing effects.
What happens when you multiply a negative by a negative?
Ans: When you multiply a negative by a negative you get a positive, because the two negative signs are cancelled out. So, negative multiplied by negative is always a positive.
