Real-World Examples
Example 1: Adding Fractions
Let’s add -1/2 and 1/3:
-1/2 + 1/3 = -5/6
Example 2: Subtracting Fractions
Now, let’s subtract 1/4 from -1/5:
-1/5 - 1/4 = -9/20
Example 3: Mixed Operations
Finally, let’s perform a mixed operation: -1/3 added to 1/4 and then subtracted by -1/6:
-1/3 + 1/4 - (-1/6) = 1/12
