Hello,
Here's another way to look at it:
If you have a series of positive and negative numbers, group all the positives in one column and all the negatives in the other. Add the totals in each column (regardless of sign). Take the difference (subtract) between the two totals and apply the sign of the larger number at the end.

The answer is: IT DEPENDS. Which of the two numbers is farther from "0" on the number line? For example, let's suppose your problem is:
(-6) + (+2) = _____
If you draw a number line, you can see that (-6) is much farther away from 0 than (+2). Therefore, your answer will be NEGATIVE. (Specifically, it will be -4 in this case.)
What if we change the problem to:
(+6) + (-2) = _________?
On the number line, you can see that (+6) is farther away from "0" than (-2). In this case, the answer will be POSITIVE. (Specifically, it will be +4 in this example.)
Hope that helps!
