That’s pretty amazing. I wish we would have learned math this way when I was a kid, I know I would’ve picked up math more intuitively.

This is the stupidest way of doing multiplication. I hope Common Core stays in America.

This is how an idiot would teach multiplication to a moron.

…and that just added two extra steps to the math problem.

I gotta say, even though I already basically understood what the long multiplication was doing, and basically do the same thing whenever I do mental multiplication, seeing it laid out like this gives me renewed respect for it. It’s really an ingenious little algorithm for quickly computing a product by hand.

The graph paper explanation is a good tool to understand what a number represents as far as One’s, Ten’s, Hundred’s, etc however, this should of already been taught when teach basic Addition and Subtraction. Once again educators are trying to put the cart before the horse.

Learn the multiplication and division tables and don’t worry.

this is making things way more complicated than they need to be. 16 x 30 you can do in your head. minus 16 x 3 and you get the answer.

areas of sections. math doesnt need a backstory?

all other videos about this say that this for 3rd and 4th graders, i’m struggling with this and i graduated high school last week

Anyone make a “multiplication with the area model” t-shirt? I think the visual of connecting this to the standard algorithm is super compelling, especially with color coding for each of the partial products. I’d be stoked to wear that on my back!

Helpful for understanding

We just released a music video which teaches you the area model through a song about a farmer planting green beans and black beans! It’s a great supplement to the excellent visual instruction you’re watching by Khan Academy.

Thanks needed it for school😀😀😀😀😀

This video was so helpful. I had to learn this to help my daughter with her homework. Other videos did not help, we kept getting wrong answers….we got 8/8!!! Thank you!

Thank you I need this for school I am learning it.

My math cllub teach uses your videvs for math

think it very helpfull

This is stupid , this would confuse any kid
