Exploring Area Model Multiplication

This video tutorial explains how to multiply numbers using the area model multiplication method. It begins with a simple example of multiplying 29 by 8, then progresses to more complex examples such as 37 times 9, 26 times 18, 32 times 45, 132 times 43, and finally 243 times 362. Each example is broken down step-by-step, demonstrating how to split numbers into parts, multiply them, and add the results to find the final product. The video emphasizes understanding the structure of the area model and checking results with a calculator.
