What are the most interesting and mind expanding areas of mathematics? I have to admit I'm a little bit of brainlet when it comes to finding the effort to want to learn math, and I can't afford to go to school where there is time, freedom, and a requirement to do well and study. But if one of you know of any really good reasons to study it, maybe concept to get to which are really extravagant in the way they open up a new mental world of thought to you, I'd love to know about them
