Methods for Solving Subtraction Problems

The video tutorial focuses on solving a specific problem using two different methods. The first method involves converting a subtraction problem into an addition problem, while the second method simplifies the subtraction by adjusting the numbers involved. The teacher emphasizes understanding the process over finding the correct answer and encourages students to explore different approaches to problem-solving.
