This video is another in the series looking at Matrices. This video looks at how we can multiply matrices together. I look at how to multiply matrices together and how to check if the matrix product is defined (or not). I then look at matrix powers (and what they are used for) and then the identity matrix (which is going to be really important for the next few videos and the work in Year 12). There are lots of worked examples and I do all I can to explain the content in the best way possible.
