<u>How to do Negative Addition</u>
Negative Addition is almost like Positive addition. The only catch in Negative Addition is that it is like subtracting. Let me make this clearer. If you draw a number line, with the positives and the Negatives, it will look somewhat like this. (Attachment down below). As you see, the Positives are increasing to the right, but the Negatives are increasing to the left.
When you do addition, you increase right? Like you have 8+4 which is 12. In positive addition you increase to the right, (look on number line). So, if you reverse it to -8+4 you would have to increase to the right, not the left. -8+4 is not -12 because when you add, you increase not decrease. (-12 is smaller than -8 and 4).
So that means -8+4 is -4.
Trick: Subtraction
Another way to think about it is replacing the addition sign to a minus sign then make the negative go away. So, we get 8-4 which is 4. And then we put the negative sign at the 4, so we get -4.
