Please excuse my terrible english skills.
About a year ago, I decided to study basic mathematics. At this time, I was not even able to find a solution of some tricky linear equation.
I studied basic algebra, euclidean and analytic geometry, linear and quadratic, polynomial functions, trigonometry and some basic calculus. (Also stochastics, but we dont have to regard it) These stuffs cover most of the high school mathematics at least in my country. And it should be sufficient knowledge to study so called introductory real analysis.
I never had college calculus. And I am also not willing to spend my time for it. (Stewart, Thomas.. etc.)
Now I am learning university mathematics for myself since few months due to interests in the subject. First I studied naive set theory with the first chapter of Munkres,Topology. Then I jumped directly into Baby rudin. I didn't have any serious problem until chapter 2, basic topology was pretty enjoyable. I could solve most of the exercises. Nevertheless I got stuck in Theorem 3.20 (Some special sequences). I can just barely understand things from this part until now, although I tried and tried.
Is there some easier book than Rudin, which is written for absolute beginners with weak calculus knowledge? And can someone explain me why I can't go through that chapter? I want to learn Real Analysis. Please help me
