on a number line,
negative means go left
positive means go right
-4 means go 4 units left of zero
-6 means another 6 units left of 0

If you need to know the sum you need to add. So if you are adding two negative numbers, basicaly, you are doing subtration.
4 - 6 = -2
So we just flip the negative 2 into a positive 2.
