Matrix Multiplication

In this lesson I will teach you how to multiply matrices.  This can be really confusing for students the first time they see this so I would plan to review the lesson a few times.  In the previous lesson we looked at matrix operations with the exception of multiplication.  Matrix multiplication is different than scalar multiplication and much more involved.  I don’t think the procedure is difficult it’s just that you need to focus and concentrate.  If you’re not paying close attention to your work these problems can easily go wrong- even for me and I’ve been doing this stuff for 30+ years!  There are a few key properties you need to learn about matrix multiplication so take good notes.  I can’t stress enough how important it is to practice this skill neatly and with patience. Good luck you can do it!
