Exploring Multiplication Through Addition

In this video, Piggy asks the professor for multiplication problems using donuts. The professor explains that multiplication doesn't depend on the objects used. Piggy then explains multiplication using candy, but Kelly struggles with this method. The professor introduces an alternative approach, explaining multiplication as repeated addition. The students practice with examples, and the video concludes with an invitation to use a training app for further practice.
