If there is anything you want to know about Matrices, then it's included in this video! I start by looking at the form of a Matrix. Moving on to look at how to define a matrix, what an element is. Why are rows and columns so important. What does it mean for a matrix to be defined. How to add, subtract and multiply by a scalar before moving on to the idea of Identity matrices, square matrices and finally look at multiplying them together.
All in just a few minutes! If it's not in this video, then it's not worth covering. I hope you enjoy it.
