Part ONE: What is repeated addition?
Part TWO: How is repeated addition related to multiplication?
Repeated addition is when you add the same number more than once.
It is related to multiplication because repeated addition is combining equal groups. That's what multiplication is. You can add over and over again, or you can multiply by the number of times that you have the same group.
