Add a solutions chapter?

[JASory]

As the target audience is in non-mathematical sciences, it might be helpful to provide a solutions chapter to demonstrate the approaches used for some of the exercises and challenges.

Additionally an appendix might be useful for information that is tangential to the topic but too complex to cover in a footnote, as is the case in Cantor's diagonal on pg 105.

I can add both if you are interested?

Do you mean writing the solutions or just the structure? I don't mind the latter, the former (actual exercises and solutions) I already plan to do, based on many years of tutorials on the topic. At the moment there are no solutions just because I didn't get to this part yet ;-)

Concerning appendices: you are absolutely right, and I would appreciate the addition if you're interested.
