Same rules as adding whole numbers with different signs.
Then you are adding two rational numbers with different signs! No big deal!
If the two numbers have different signs, then the result will be negative. If the two numbers have the same signs, the result will be positive. This assumes all the numbers are non-zero.
You add as normal , pretend as if the signs weren't there,but the answer will be a negative!
