We will take the challenge to work on more than simple basic math. So we can verify that the method works in arbitrary situations. So our original material will be the amsmath matrices. We will illustrate a matrix transposition by highlighting submatrices and drawing arrows.

How to do it...

We will use TikZ for this. Such a big graphics package may seem to be a bit heavy for such a purpose at first. But it provides us with consistent styles and allows us to do nearly anything graphically.

Let's do an example step by step:
