Here is an example of how to add and subtract positive and negative numbers.  Remember to read the lesson on this topic.

Basic steps to follow:

1. First we are focusing on the positive and negative numbers on the real number line
2. Next to add positive and negative numbers follow the rules; same sign add and keep sign; different signs subtract and keep the sign of the number with the largest absolute value
3. Turn all subtraction problems into addition problems by changing the subtraction sign into an addition sign and applying a negative sign to the number to the right of the subtraction sign (this is often called “plus negative”); then follow the rules for addition
