## How to multiply binomials using a box!

Wednesday, February 10th, 2010Many people find this more visual and intuitive than FOILing.

I split the video into 8 brief parts. Each part features one practice problem, fully explained and demonstrated on the whiteboard.

If you, your family, or your friends would like to see me make an instructional video about a particular math topic or type of problem, leave a comment to nominate your math problem for its very own video!

And if you like the video, please feel free to click on the “heart” to show that you “heart” it. <3
