This video tutorial covers the process of subtracting mixed numbers. It begins with an introduction to the steps involved, including obtaining a common denominator, checking for borrowing, and simplifying the result. The tutorial provides multiple examples, starting with cases where the denominators are the same, moving to examples with different denominators, and finally addressing situations where borrowing is necessary. Each example is explained in detail, demonstrating the process of converting mixed numbers to improper fractions when needed and simplifying the final result.
