Adding and Subtracting Mixed Numbers

The video tutorial on Math Dogs explains how to add mixed numbers by converting them into improper fractions, finding a common denominator, and then adding the fractions. The example problem involves calculating the total miles walked by Cyprus over a week. The tutorial provides a step-by-step guide to converting mixed numbers, finding a common denominator, adding fractions, and simplifying the result back into a mixed number.
