Summing Evens (Two Visual Proofs)

In this video, we show two ways to think about summing the first n even positive integers. One way is reminiscent of the classic visual proof to sum the first n positive integers while the second way is similar to the technique of the classic visual proof to sum the first n odd positive integers. So this one encodes both of those!
