Decimal Multiplication with Area Models

This video tutorial covers the concept of decimal multiplication using area models, focusing on the problem 3.4 x 2.8. It explains how to use the distributive property to break down the multiplication into partial products and then sum them to find the final answer. The tutorial also includes a practice problem, 6.3 x 4.4, for viewers to try on their own.
