Here are some rules to help you with adding and subtracting negative and positive numbers:

1 )To add a positive number, move that number of places to the right on the number line. Eg. 4 + 3 = 7

2) To subtract a positive number, move that number of places to the left on the number line. Eg. 4 – (+3) = 1

3) To add a negative number, move that number of places to the left on the number line. Eg. 4 + (- 3) = 1

4) To subtract a negative number, move that number of places to the right on the number line. Eg. 4 – (-3) = 7
