A few months back, I published my website, teachyourselfmath, which shows you a list of math problems parsed automatically from PDFs around the world. It received a tremendous amount of feedback and interest. And I was honestly overwhelmed by the response and then life happened.<p>Over the past few weeks, I have been actively working on this project, trying to incorporate all the feedback and I’d love to share it with the world again. New features:
1. Filter problems by difficulty and category
2. Bookmark your favorite problems
3. Editor in the comment section supports markdown formatting
4. ...and some UI improvements throughout the website<p>I am also starting a small telegram community of math nerds who would like to discuss all things math, as well as talk about upcoming features and feedback for the website. Here is the link - (<a href="https://t.me/teachyourselfmath" rel="nofollow">https://t.me/teachyourselfmath</a>)<p>If you’d like to support my work through small donations, you can do it here - (<a href="https://www.buymeacoffee.com/viveknathani">https://www.buymeacoffee.com/viveknathani</a>). Right now, teachyourselfmath runs for free. Later, I’d love to make features that people would love to pay for but fundamentally, the goal is to make math accessible through technology. There’s a lot of peer learning involved in the comments section of these math problems. All of this gives me more reason to keep working on this.<p>Happy hacking!
Are you interested in using <a href="https://vector-graph.com/" rel="nofollow">https://vector-graph.com/</a> to add math diagrams? I created it exactly for this kind of websites and I'd be happy to waiver the fee for your site!
To stay in touch with math, the annually publicized math problems from the German Abitur[0] are great!
The problems are already separated into three difficulties, making it suitable to include in your website (although they might need translating).<p>[0] <a href="https://www.iqb.hu-berlin.de/abitur/pools2023/mathematik/erhoeht/" rel="nofollow">https://www.iqb.hu-berlin.de/abitur/pools2023/mathematik/erh...</a>
cool.<p>highly recommend to implement the review exercise style of <a href="https://www.executeprogram.com/" rel="nofollow">https://www.executeprogram.com/</a>!, both the UI, albeit with better theming (<a href="https://monkeytype.com/" rel="nofollow">https://monkeytype.com/</a>), and the spaced repition feature, all while keeping the hn styled comment section, although i'd let none-related comments run horizontally to click through different approaches/explanation(-styles).<p>you got a startup there. keep it affordable. 5 bucks a month after u get a propper UI and spaced repetition with different numbers integrated.<p>great, simple, idea! let the copycat-wars begin :D
I remember when you first posted this and it is a project I think upon very frequently! It's nice to see you have made further progress — and that there are comments with attempts at solving! Great job.<p>I still find some problems with the navigation of the problems, but I am not even sure where to go to fix that. It has to do with the difficulty of each problem, but also with how large each topic is: algebra encompasses both linear algebra and linear equation solving, which is a very wide bracket.<p>But you're making progress. That's great! Congratulations on that, and I'll be sure to keep visiting the website.
Nice work. Out of curiosity, how is the difficulty determined? I notice that some of the "hard" questions (inverting a 2x2 matrices or differentiating common functions) are much easier than others (proving that no natural number has Euler totient equal to 14).
Looks good, one quick thing: Maybe hide the comments behind a button? Now they are giving away the answer, as some have already posted it there in the first comments.
I love it! I also built a math focused website. Schools can use it to host Math-A-Thons, which is a type of fundraiser where students answer math problems online and solicit donations to support their school. I made all the math problems available to play for free outside of the platform, as well as guides that help the students answer the problems:<p><a href="https://www.forourschool.org/math-games" rel="nofollow">https://www.forourschool.org/math-games</a>
<a href="https://www.forourschool.org/math-guides" rel="nofollow">https://www.forourschool.org/math-guides</a><p>Yay Math!!
As someone who has struggled with learning maths, this looks really great. I've set up an account and look forward to giving it a try<p>And yes, the Hacker News minimal style of the website is very much appreciated! well done
This looks fantastic, getting better at maths is something I have always wanted to do.<p>Also, some of the commenters have posted python code but it is not formatted/styled.
