Adding & Subtracting Integers
To add integers, remember these rules:
- If the signs are the same, add the numbers together and keep the sign.
- If the signs are different, subtract the numbers and use the sign of the larger value.
To subtract integers, remember this rule:
- To subtract an integer, add its opposite
(If you follow that rule, then you will remember that double negatives cancel each other out.)
