Title: Added an explanation of the logical NOT operator plus other minor improvements 

I added a paragraph on page three (which is probably best to be translated into German by a native speaker) explaining the logical NOT operator, because we hadn't mentioned it anywhere before using it.

Also just fixed some typos and improved some consistency of how variable and function names are represented.
