The video tutorial explains how to subtract mixed numbers by rewriting them and using regrouping. It begins with an introduction to the problem, followed by a detailed explanation of rewriting mixed numbers to separate whole and fractional parts. The concept of regrouping is introduced to handle cases where the fractional part of the subtrahend is larger than the minuend. An alternative method is also presented, demonstrating another approach to solve the problem.

What is the initial problem presented in the video?

• Dividing mixed numbers

• Subtracting mixed numbers

• Adding mixed numbers

• Multiplying mixed numbers
