### About Adding Mixed Numbers:

When we work with mixed numbers, we generally keep them as a mixed number when performing addition or subtraction. When multiplying or dividing, we generally convert the mixed number into an improper fraction. Keep in mind you can always convert the answer back if required by the assignment.
