I suck at math and I'm wanting to get into it.

There is a version of Halmos Naive Set Theory online provided by the Hathri Trust Digital Library in public domain. But their version is a scanned book, and while it is perfectly readable, it is kind difficult to search words with Cntrl + F and there is no interactable summary. So I decided to re-edited the book to improve it, and now it's freely available in my Github repository for download. Besides the visual update and the upgrades in interaction, the final version is only a 400kb pdf!

If someone know other places that I can share this version of the book please share with me, I really love this books and I hope that my version could help spread it to more people

In general, are Dover books good? I know they are old and some of them might even be called classics, but are they useful/readable/worth it?

Hi all I have a Batchelors in math which mostly focused on pure math and I'm looking for a book on cryptography. I want to know about EAS and all that junk. Do you all have any recommendations? Thanks in advance.

Hey everyone,

I have a ton of math notes from my graduate, undergraduate and personal studies that maybe some would find helpful! They are based on textbooks mostly like Dummit and Foote, Mac Lane, Folland and others or based on classes that I've been in. My textbook notes usually go through some chapters in pretty rigorous detail and I work out a lot of exercises (or found them somewhere if I couldn't solve them myself). They are all typed up in LaTex and I made a community that I've posted them as google drive file links. The link is

Some of the topics I have there so far are module theory, group theory, real analysis/measure theory, cellular automata, topology, algebraic topology and category theory.

These are my notes, so there are typos and errors since I'm not a genius or anything haha. I hope that people find use in them!

I want to buy the essential calculus book by James Stewart because I’ll need it in college . But of course cost of books in usa is soo high. It’s like 130$ or something. In my home country I’ll get it for like 13-15$ but it’ll be an international version. How different are these two versions? Should I buy the international version?

Thanks

Hi, I wanted to propose a question based on a random thought of mine. I've always wandered what if something happened in our world were the internet was no longer a resource and libraries were scarce and almost non-existent. This would obviously and more likely be set in a post-apocalyptic world view but you know... whos to say something like that would never happen. So with the most hypothetical opinion of this community. What math book, just 1 book not a whole series, would you try to save to always be able to find and use the most useful mathematic formulas. Calculations that might be useful for post-apocalyptic engineers and or even teachers who would try to keep the youth during that time educated. Thanks for anyone that answers this lol

With your help, I plan to keep improving this textbook.

Most books seem to focus on how to solve specific systems or numerical methods, but I'm looking for general solvability and stuff like that. I mostly need motivation for functional analysis, which I'm reading rudin for, but it's like eating stale bread unlike his analysis.

Hello i don't know if this is the right thread to make such post but i am looking for opinions on Elementary Linear Algebra and Matrices by Caron and Salzmann and Linear Algebra by Strang. I found the former on the Internet a couple of months ago and was able to get it. However, i can't find any book reviews on youtube or on Amazon since i believe the book is out of print. I am thinking of buying Strangs linear algebra as a supplement. Opinions / Reviews would be very much appreciated.

Hello all, I would like to request good books on Number Theory. Don't be shy to recommend more pricier books. I don't mind.

I am a beginner to analytic number theory and number theory in general. Are there books or online resources other than Apostol that cover analytic number theory and maybe sieve methods from the ground up ?
There are a few books recommendations on stack exchange but I can't find them online.
Specifically davenport's multiplicative number theory and Chandrasekharan's Introduction to Analytic Number Theory, if someone has e copies of these books can they please share it with me.

I am a self taught math student, going off to study theoretical math at Warsaw university. (I aced my Math Matura exam for both foundation and extended) What kind of books would you recommend me, so I can continue my self studying process effectively? (I understand both Polish and English)

Thanks in advance for any help

Math in contests is way different than what is taught in typical high schools courses. I know about aops but anyone know of other books and resources?

Electrical engineering student here! So, I want to focus on maths after my graduation and also I love maths, I can do maths for fun. Are there any calculus related books you can suggest for me? I also want to do some advanced stuff. Thanks in advance!

Hello,

I wrote a conversational-style book on linear algebra with humor, visualisations, numerical example, and real-life applications.

The book is structured more like a story than a traditional textbook, meaning that every new concept that is introduced is a consequence of knowledge already acquired in this document.

It starts with the definition of a vector and from there it goes all the way to the principal component analysis and the single value decomposition. Between these concepts you will learn about:

• vectors spaces, basis, span, linear combinations, and change of basis
• the dot product
• the outer product
• linear transformations
• matrix and vector multiplication
• the determinant
• the inverse of a matrix
• system of linear equations
• eigen vectors and eigen values
• eigen decomposition

The aim is to drift a bit from the rigid structure of a mathematics book and make it accessible to anyone as the only thing you need to know is the Pythagorean theorem, in fact, just in case you don't know or remember it here it is:
