E-Math: How To Multiply Matrices (Video)

This is my first attempt this year to produce a video. Should the response be good, I will use video to share more tips and strategies with my audience, so please leave me a comment.

Please pardon me the 'echo' effect in my introduction and also the low resolution. I was using my new logitech webcam :D

I'm working towards producing better quality videos. Share tips on this if you have any. Would appreciate it.

I look forward in hearing your comments and the answer to the question in the video.
