How is adding positive and negative integers different from adding only positive integers on a number line?

1) To understand how that works, let me draw a number line:

If we only add positive numbers like 2 +3 = 5, 6+8 =14, etc. we'll only get a positive result (right to the zero) on the number line, we are moving to the right

2) If we add positive and negative numbers, for example:

2 +(-3) =2 -3=-1

0+(-1)= -1

6+(-2)= 4

On the number line, we are starting from one point and moving to the left.
