The chapters contain exercises, which have to be solved to get from page to page.
Some solutions like \(\sqrt{2}\) or \(\alpha+\beta\) can't be entered as plain numbers and therefore need to be typed in latex code.

The chapters are designed in a way, that people without any experience of latex might learn it by many examples without needing any other help like in this exercise:

\(\sqrt{2\cdot\alpha+\alpha}=\)
