Books only ever teach you the absolute minimal as anyone who has ever attempted the questions at the end of a chapter will find that the topics being questioned are rarely covered in the preceding chapters.
Say for example, a chapter teaches you all about the addition operator and that 2 + 2 = 4. But then in the questions, they ask you to take the leap of faith to solve what 2*2 is without ever introducing you to the * sign.
Simply put, the smug author always wants you to telepathically arrive at the right answer for their "trivial" questions, and then blames you as the "lazy" student for not trying "hard enough" to solve a question with information you never had access to begin with.
You are supposed to use your brain to figure some things out yourself. It's part of the learning process. You can't expect to be spoon-fed every single thing.

Nothing like this ever happens. You're just dumb.

Hey friendo go ask a bunch of other people if they are having the same experience as you and if the only people sharing your concerns are fucking retarded then you know that this isn't a real problem and you're just retarded as well.
