Q. How to add fractions Involving Negative Numbers?

Ans.

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


Adding fractions

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

1. Positive (+) + negative (-)

2. Negative (-) + Positive (+)

These first two cases are basically the same.
