It's a really nice idea and very good to see a familiar and simple interface, I'm definitely keen to look at this when I'm "idling"! Two suggestions that I don't think have been mentioned: 1. It might be nice to at least acknowledge the source of the problems PDF-wise, no doubt somebody put effort into developing then and the supplementary information (assuming the PDFs are open source) would be useful for learning 2. Supporting information for learning the context subject material around the problem would be good: this relates to other comments about curation. This doesn't feel like "teach yourself math" so much as "test your math", which is still really helpful, but if you don't know the material there's nowhere to turn too Great foundation for an amazing platform, nice work!

Strong agree on (1). I don't mind the copyright violation personally, but as an academic who develops these types of problems, attribution would be the polite thing to do.

  > I don't mind the copyright violation personally, but as an academic who develops these types of problems, attribution would be the polite thing to do. Is there a copyright violation? Totally not a copyright lawyer (or any kind of lawyer) but I thought basic facts, mathematical relationships, etc. were not eligible for copyright. At least for something like: Find the derivative of X^2 + 2x + 3 I think the problem and the solution aren't subject to copyright. I guess a complex word problem might be though, since the prose part would normally be subject to copyright anyway? Not sure being part of a math problem would change that. I dunno. I could be totally wrong about this. Any copyright experts around to chime in? Google's Generative AI feature says the following, but not sure how much trust to put in that. --- According to Bytescare, mathematical formulas, problems, proofs, and theorems are not copyrightable. This is because math is considered a "truth" and is not necessarily invented but discovered. However, the content of a math book, including diagrams, word problems, and illustrations, can be copyrighted. According to the Copyright Advisory Network, word problems may fall under copyright, but problems containing only numbers and symbols probably do not. ----

  I don't disagree that attribution would be polite (in fact I think a lack of attribution is impolite), but I don't believe mathematical problems are generally copyrightable.

    I'm sure it depends on the situation, but I doubt for example that you could legally copy 50 pages of problems out of one book and sell them in another book verbatim.

1. sources of problems will be out soon. 2. that is an interesting idea. i have been meaning to work on the general problem of letting users work their way through a problem on the website itself. thank you for your feedback!
