What happens when you add negative plus a negative?
When you are adding a negative number to a negative number, it becomes subtraction, where you start from a negative point on the numbers line and move left. For example, -3 + (-2). This reads “negative three plus negative 2”.
Are negative numbers in parentheses positive?
If we have a minus sign before the parentheses then we the signs within the parentheses will change. Two negatives make one positive!
Is a negative plus a negative make a positive?
Similarly, we can prove that a negative times a negative is a positive. Since we know that −ab is negative, and the sum of these two terms is 0, therefore (−a) × (−b) is positive.
Why negative plus negative equals 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.
What happens if you subtract a negative from a negative?
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.

Why negative minus negative equals positive?
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. So, instead of subtracting a negative, you are adding a positive. So we’re changing the two negative signs into a positive, so the equation now becomes -2 + 4.
Why when you subtract a negative is positive?
Subtracting a number is the same as adding its opposite. So, subtracting a positive number is like adding a negative; you move to the left on the number line. Subtracting a negative number is like adding a positive; you move to the right on the number line.
What does a positive plus a negative equal?
