Problem-Solving with Decimal Operations

Mr. War introduces a math video focused on problem solving with decimal operations. He sets up a real-world problem involving the cost of books and pens, demonstrating how to solve it using inverse operations. The video includes a detailed walkthrough of the solution, verification using a calculator, and an explanation of inverse operations. A second problem is introduced, following a similar pattern. The video concludes with a farewell and encouragement for future learning.
