Here is another clever way to multiply two numbers. Can you figure out why it works before I give things away in the second half of the video?

![Partition Numbers Part II: An Accessible Overview (Tanton: Mathematics)
[Part II of IV] In January 2011 there was a breakthrough in a famous, tough, unsolved problem in mathematics - finding a formula for the partition numbers. In this series if mini-videos I give an accessible introduction and overview of the mathematics and history of these numbers. We start with childs play, move to the work of Euler and Ramanujan, and then in the final video, attempt to give a sense of what the recent breakthrough is for all those who dont have the high-powered mathematics at hand.
