This video goes through a couple of examples step by step showing how to multiply matrices. It also shows the simplicity of entering matrices using a TINspire as opposed to other graphing calculators. The resources are especially helpful, with many example problems and tutorials. This is a very good video from a student who has seen matrices before but is struggling with how to multiply them.
Terrible  audio and video do not match, but what is worse is that there is not enough video displayed as the lesson unfolds. Also audio has a wavy sound.
