Math sort of has to be learned in the opposite way from how it's written. It's best written "short and sweet", compressing as much meaning as one can handle precisely into a single theorem for maximum generality. Human minds, though, learn mental models of how things work from relatively concrete examples, ones which require only a little new information to be absorbed in order to gain the new concept.
A lot of things you thought were separate and overly-elaborate start seeming simple and small once you actually work your way up enough levels, to have seen enough examples, that the generalizations make sense to you. But that requires a lot of work!
