The video tutorial explains how to break down multiplication facts using arrays and the distributive property. Maria wants to set up seven rows of four chairs but doesn't know the product of 7x4. By visualizing the chairs in an array, she learns to split the multiplication into smaller, known facts. The distributive property allows her to break 7x4 into (5x4) + (2x4), resulting in the same total of 28 chairs. The tutorial emphasizes that different methods yield the same result, reinforcing the concept of consistent outcomes in multiplication.
