Einträge mit dem Tag ‘Multiplikation’

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.
