I'm an undergraduate at Rutgers University. Abstractly speaking, I am interested in how "local" and "global" interact in mathematics. More concretely, and in line with this theme, I am interested in the interface of topology with analysis and geometry.

 22h comment What could be better than base 10?I'm not really sure, but mental arithmetic is no easier in any other base - the only difference is the number of digits for larger numbers. I say let people use a calculator. Arithmetic is the job they were born to do, and the job we were born to automate. 1d comment Radius of convergence and complex power seriesThe proof is, in fact, identical to the real power series case. 1d comment Going back to the basics?Search for the topics I listed on Amazon or someplace like that. Your local university textbook list might also be helpful. The books you listed aren't really introductions to mathematics in the sense that they prepare you for further mathematics. They are introductions in the sense that they try to describe the job of a mathematician. 1d comment What does it take to get a perfect score on the Putnam?I think this question should close, but the OP asks least one question we can answer concretely here. No, mastering all of undergraduate and graduate mathematics is not necessary. The Putnam is meant to be solvable for anyone who knows basic calculus up to multivariable, group theory, and linear algebra. Knowing some analysis and combinatorics and such goes a long way, but more abstract topics like topology, functional analysis, or ring theory will at best be tangentially relevant. 1d comment Inequality in a bounded real sequence@zyx Perhaps, but I think people are responding more to two potential flaws about this post: 1. It is written in the imperative, and while some don't mind others do see this as a little bit rude. 2. Context helps people refine and improve their answers. Knowing the lines the OP has attempted and the source of the problem goes a long way to help people craft a better response. Maybe we can start replacing this "what you have tried" meme with something more specific. 1d answered Going back to the basics? 2d comment Zeros of the decimal representation of $k!$Probably better as a comment than an answer, since it does not actually answer the OP's question. 2d comment Is game theory a part of math?@LeeSleek In my opinion real life is an interesting field, but not very applicable to math. 2d comment Zeros of the decimal representation of $k!$How exactly is this relevant? Also, this sort of self-promotion is explicitly frowned upon on MSE: please read math.stackexchange.com/faq#promotion. 2d comment How to solve these elementary algebra questions?Also, a user has edited your title to better reflect the content of your questions. In general, questions should have titles that tell users at a glance what the topic will be. 2d awarded Custodian 2d reviewed Edit suggested edit on How to solve these elementary algebra questions? 2d revised How to solve these elementary algebra questions?Changed the title to something a bit more specific than "please help" 2d comment Why is it important that a basis be orthonormal?"Have your say" sounds like you're looking for opinions or trying to generate discussion, neither of which are this site's focus. Also, your question is extremely vague. Please provide some context. 2d comment Infinite dimensional vector space, and infinite dimensional subspaces.By induction, you need only show the existence of one such subspace. 2d comment What is the terminology for the non-repeating portion of a rational decimal?Learn something new every day...thanks Zev. 2d revised Differentiating a complex equation in order to optimize for the parameterImproved formatting. 2d comment Is this piecewise-defined function on $\mathbb{R}^2$ continuous at $(0,0)$? What about differentiable?You should delete your earlier answer to avoid confusing the OP. 2d comment About continuous functions and aritmethic progressionWhat is $k$ here? If I let $k=1$ or $k=2$ this is trivial. May21 answered Math blogs, pros and cons for writers?
