Mathemagic with Arthur Benjamin (video)

This is a pretty amazing performance of "mathemagic" – calculating things in one's head by Arthur Benjamin. He not only can calculate but also ENTERTAIN, so this video is sure to captivate you! I enjoyed it a lot, and my children watched it multiple times in a row. :)

I also posted the video on my website with some more commentary:
