Adding fractions involving negative numbers, and subtracting them, are only slightly different. But, I'll write down separate instructions for adding and subtracting.

There are three different kinds of additions you might see involving negative numbers

1. Positive (+) + negative (-)

Here's an example: Notice that if the negative fraction had come first, it would have been done exactly the same way:

3. Negative(-) + negative(-).
