Multiplying Using Arrays

The video tutorial explains how to solve multiplication problems using an array model by decomposing factors. It provides step-by-step examples for multiplying numbers like 5 * 12, 12 * 15, and 10 * 725. The process involves drawing a rectangle, decomposing factors into tens and ones, multiplying each part, and summing the partial products to find the final result. This method simplifies multiplication with multi-digit numbers.
