Mastering Multiplication with Expanded Form

Mr. Ahmed teaches how to multiply multi-digit numbers by a single-digit number using expanded form. The lesson includes several examples, such as multiplying 5 by 143, 3 by 1250, 4 by 213, 4 by 59, and 3 by 288. Each example demonstrates breaking down the multi-digit number into expanded form and multiplying each part by the single-digit number, followed by adding the results to get the final product.
