How to do multiplication with muLets multiply 36x27

Here we make an accurate scale diagram to show how to multiply multiple digits. Then we add up all the chunks and show how long multiplication works.

If you don't have any grid paper at hand, you can do use GridMaths.com which is what I'm using here.

Often school students learn long multiplication as just a complicated method they have to remember the steps - the whole idea of this video is to make it really obvious where all the steps come from.

Making these kind of diagrams will be really helpful if your struggling with multiplication.

Part 2 shows the simpler way where you draw the diagram, but it doesnt need to be to scale - so much faster and simpler, but you still see where all the pieces come from.

enjoy,
