Multiplication as Repeated Addition

The video tutorial explains how multiplication is related to addition by demonstrating that multiplication is simply repeated addition. It provides examples, such as 3 * 7 and a Halloween candy problem, to illustrate how multiplication problems can be solved by adding repeatedly. The tutorial also highlights the commutative property and offers practice problems to reinforce the concept.
