Adding and Subtracting Mixed Numbers Using the Number Line

The video tutorial explains how to represent mixed numbers on a number line and use this representation to add and subtract them. It demonstrates adding 1 and 1/5 to 3 and 3/5, resulting in 4 and 4/5, and subtracting 1 and 3/4 from 3 and 1/4, resulting in 1 and 2/4. The tutorial emphasizes understanding the number line's division based on the denominator and visualizing the addition and subtraction processes.
