Nice effects and nicely explained. It was a little hard to hear him speak at times, so made it a little hard to follow.

I really like the clever trick explained in this video. It is neat and I don't think it is something that is commonly known. I think it would be helpful if there was at least one more example. This way, it would be easier to have an intuition about what number to multiply by. It seems it might take practice to get the hang of, but I like this technique.

 Wow, that is a really neat trick. I had never seen that before. He did a nice job explaining it too. He was easy to follow; I like that the bubbles directed our attention to the important parts of the problem. The only part I would change is when he subtracts x from both sides, to make it clearer that x=.111. I got a bit lost when he subtracted .111 from the right.
