The video tutorial explains how to multiply multi-digit numbers using partial products. It begins with an introduction to partial products and a review of basic multiplication concepts, including the power of tens. The tutorial then provides two detailed examples: multiplying 78 by 34 and 162 by 84, demonstrating the step-by-step process of breaking down numbers into their individual values and calculating partial products to find the final product.
