Japanese Multiplicator

This method, which we can find origins in the Maghreb back in the 13th century, is in reality, not Japanese. Still, it is a fantastic method to learn and experiment with multiplication in a simple and visual form.

This project takes it to another stage by explaining how to make a physical object to encourage the learning of multiplication. The format is also quite unusual as you can make multiplication up to 999 x 999.

Thanks. cool introduction to an alternate method. Is it possible to divide with that tool?

[Innokick]

Thank you for asking this question, the multiplicator can unfortunately not divide.

If this wasn't for teachers for teaching i wouldn't feel compelled to write:

Teaching deliberate bogus attribution seems... unhelpful.

"Mahgreb Multiplicator" even alliterates. And teaches a meaningful bit of geography. With a segue to some history. What's not to like about that?

[Innokick]

Thank you for the feedback! I hope you enjoyed the multiplicator anyway :)
