Today, I would like to present a funny — if somewhat useless — mathematical toy.
Originally, I wanted to create some sleak pictures to illustrate a graphic method for multiplying decimal numbers — but someone has been faster than me, posting a video at Youtube.
Therefore, I leave my pencil alone. I shall merely add that this method works in exactly the same way as the usual pencil-and-paper way does.
