I got a 12 my senior year of high school, but I was one of the top 2 students in Math 25 (they don't actually keep track, but we were all friends in the class so we compared how we did), so there's plenty of room.\r\n\r\nWhat I would most encourage is that you get really good at *proofs*.  I don't know what 25 will be like next year (in my time, it was taught by a different professor every year so it was always different), but it will be proof-based and it will be challenging.  Your knowledge of multivariable calculus will be helpful in your *other* classes, because you probably won't learn anything directly applicable in 25!  But you'll be doing a ton of topology proofs, so make sure you're good at that.  Maybe find a (cheap Indian) copy of the [Rudin](https://www.amazon.com/Principles-Mathematical-Analysis-International-Mathematics/dp/007054235X).  I'm serious, get it shipped from India if you have to, but do *not* pay the amount they're selling it for on Amazon, holy shit.","subreddit_name":"Harvard","author":"xiipaoc"},{"body":"Rudin has published many books on analysis each quite different.

I found a beautiful pdf of this that one can download and [for sale brand new for $142.49](https://www.amazon.com/Principles-Mathematical-Analysis-International-Mathematics/dp/007054235X).  \r\n\r\nYes, go forth and pirate!","subreddit_name":"technology","author":"silverwoodchuck47"},{"body":"IMO the absolute best book for intro to real analysis is [Principles of Mathematical Analysis by Rudin](https://www.amazon.com/Principles-Mathematical-Analysis-International-Mathematics/dp/007054235X)\r\n\r\nI think real analysis kicks most people in the butt. Its really abstract and jarring in relation to any lower level math. Its kind of your introduction to higher level math and the type of thinking that analysis forces you to use.\r\n\r\nThe way I got better? Practice writing more proofs and then do it again. Rudin has some awesome problems in it, and you can teach yourself some incredible things about the inner workings of calculus.","subreddit_name":"math","author":"mightcommentsometime"},{"body":"You need some math but not all math.  Statistics uses only probability theory, and that uses only real analysis.  You don't need algebra except linear algebra, combinatorics, complex, or many other areas of mathematics.  If you do a PhD in statistics, you will be expected to take a course in measure-theoretic probability.  A prerequisite for that is advanced undergraduate real analysis, for which an appropriate textbook is [\"baby Rudin\"](https://www.amazon.com/Principles-Mathematical-Analysis-International-Mathematics/dp/007054235X/).  So it would be helpful if you had that course (whatever it is called where you are) and all of its prerequisites, prerequisites of prerequisites, and so forth.  You need a lot less for a masters in statistics.  Multivariable calculus should be enough for that.\r\n\r\nOTOH, even having a PhD in math isn't a good preparation for statistics.  Some familiarity with the ideas of statistics is helpful.","subreddit_name":"statistics","author":"berf"},{"body":"This is super helpful, thank you!\r\n\r\nAnd nothing against simulation, I know it's a powerful tool.

They are all just abstract real things.\r\n\r\nAnd, as complex numbers exist separate of your experience, they are also quite real from a philosophical standpoint. They are not platonic ideals that I have defined, but rather a result of the nature of space-time. They would work the same in all bases, if we redefined all the operations on them, and so on. In fact, [Rudin](https://www.amazon.com/Principles-Mathematical-Analysis-International-Mathematics/dp/007054235X) (which most people use to study analysis) has you prove these facts outright. [The linear analysis book I teach from ](http://linear.ups.edu/html/fcla.html) also shows many of them.\r\n\r\nIn conclusion, they are real philosophically. They are real by denotation (definition if you must). I have shown these points with sources, while you have only your ableism and your stubbornness, no evidence nor argument. \r\n\r\nIn short, get lost until you learn how to execute persuasive language instead of crying when you don’t get your way.\r\n\r\nI","subreddit_name":"mathematics","author":"Pi_astrophysicist"},{"body":"I read down below that the highest \"math class\" you took is calculus 3. Well, looks like you haven't started learning math yet. \r\n\r\nGenerally, calculus is applied real analysis. Here, \"applied\" is too big a word since calculus is made up of very simple problems tailored for high school math students and/or college students who aren't math majors(engineers, med students, biology majors etc).  \r\n\r\nIf you are in calc 3, I suggest you continue taking math classes because at around this point actual math starts kicking in, complete with theorems/lemmas/corollaries/proofs. You'll realize math proofs are held up to much higher standards of rigor and quality as compared to any other science.  \r\n\r\n[Baby Rudin](https://www.amazon.com/Principles-Mathematical-Analysis-International-Mathematics/dp/007054235X/ref=sr_1_3?ie=UTF8\u0026amp;qid=1490649231\u0026amp;sr=8-3\u0026amp;keywords=rudin) is intro real analysis textbook meant to introduce math majors to calculus as it's done by mathematicians. [Check out the table of contents](https://notendur.hi.is/vae11/%C3%9Eekking/principles_of_mathematical_analysis_walter_rudin.pdf). Notice how the whole book has a definition -\u0026gt; theorem -\u0026gt; proof structure. No other science does such rigor. Remember, though, this book is just the beginning of your journey into analysis. \r\n\r\nWhen mathematicians say \"basic algebra\", they mean topics like those in [Basic Algebra 1 by Jacobson](https://www.amazon.com/Basic-Algebra-Second-Dover-Mathematics/dp/0486471896/ref=sr_1_1?ie=UTF8\u0026amp;qid=1490649141\u0026amp;sr=8-1\u0026amp;keywords=basic+algebra+jacobson). Again, check out the TOC and the structure of the book. It's all about theorems and proofs. Major topics include groups, rings, modules etc. \r\n\r\nBut these only scratch the surface of what's out there in math: graph theory, combinatorics, measure theory, category theory, algebraic geometry, differential geometry, complex analysis etc. Each one of these subjects are humongous and ever expanding. \r\n\r\nI suggest you take a look at an actual math topic. I promise it's real cool and interesting. ","subreddit_name":"todayilearned","author":"iamnotyomomma"},{"body":"If you want to do more math in the same flavor as Apostol, you could move up to analysis with [Tao's book](https://terrytao.wordpress.com/books/analysis-i/) or [Rudin](https://www.amazon.com/Principles-Mathematical-Analysis-International-Mathematics/dp/007054235X). Topology's slightly similar and you could use [Munkres](https://www.amazon.com/Topology-2nd-James-Munkres/dp/0131816292), the classic book for the subject. There's also abstract algebra, which is not at all like analysis. For that, [Dummit and Foote](https://www.amazon.com/Abstract-Algebra-3rd-David-Dummit/dp/0471433349) is the standard. [Pinter's book](https://www.amazon.com/Book-Abstract-Algebra-Second-Mathematics/dp/0486474178) is a more gentle alternative. I can't really recommend more books since I'm not that far into math myself, but the [Chicago math bibliography](https://github.com/ystael/chicago-ug-math-bib) is a good resource for finding math books.\r\n\r\nEdit: I should also mention [Evan Chen's Infinite Napkin](http://www.mit.edu/~evanchen/napkin.html).
