How to Multiply Using Lines and Dots

One of the great things about mathematics is that sometimes, you find mathematical concepts in places that you don’t expect them to be. There are also concepts or representations that seem not connected to mathematics, but you will realize that it is indeed mathematics.

In the video below, observe how to multiply using lines and their intersections.

Don’t just watch  the video for the sake of entertainment. I encourage you to think about it.

Why does the method work?

Can you think of other concepts that is similar to the intersection of lines?

Is there a similar representation or idea that is also connected to this representation?

In the next post, we will try to answer the questions above, so keep posted.
