This introductory lesson on matrices includes a 30-minute video with 13 solved examples.

I show the basic operations on matrices: matrix addition/subtraction and matrix multiplication.

You will learn what the biggest risk is when performing matrix computations and how to deal with it. In connection with this risk, I will show you how to write out operations such as matrix multiplication in a convenient way, without having to keep many calculations in your head.
