              Example Problem - Multiplying Matrices with Different Dimensions


              By Khan Academy

              The instructor uses an electronic chalkboard to demonstrate Matrix Multiplication. At the time of this posting from WatchKnow, this video was a Featured Video on YouTube. The instructor, Sal Khan, continues from Part 1 on multiplying matrices. The student or educator may want to open the video to 'full screen' as the instructor is using a black background and the writing is small.
