What HN said

What people liked

  • Clean UI and useful resource for practising problems

    From 3 comments
    • Love the very clean UI

    • This is a great resource. I'm slowly relearning my engineering maths from 30 years ago. It is good to have source of problems to work through. A couple of suggestions. 1. It…

    • Thank you very much for this. This is so good. I wish you had a feature that allowed for bookmarking problems & comments like HN.

  • Good idea that fills a gap for self-study

    From 2 comments
    • I've thought about building something similar 100 times. So happy to see someone do it! I have a daily habit of doing math problems, just to keep the various branches I've…

    • Great idea, I would use something like this. Would be helpful to add tags/categories with grade level/difficulty if students want to use this for studying at their level.

Objections

  • Problems are sometimes incomplete or missing information

    From 3 comments
    • Why don't you actually put effort into actually writing out the problems? I'm not going to do your work for you and I'm not going to pat you on the back for scraping good content…
      ethanwillis on HN
    • This explains why some of them have missing information. Such as this one: > Suppose that one digit, indicated with a question mark, in each of the following ISBN-10 codes has…

    • I see that he's getting downvoted, but there are minor errors indeed. Problem 31 (https://teachyourselfmath.app/problem?id=31) doesn't list the problem inputs, for example.

  • No solutions provided

    From 1 comment
    • this is great, i just wish there were solutions! I personally (and i think many other students agree) rather to invest my study time only on problems which have solutions. i…

  • Copyright concerns about scraped problems without attribution

    From 3 comments
    • Hello! Thanks for sharing. This seems like a great resource, and I love that it is open-sourced; I could find myself wanting to help develop this further, as I also have some…

    • 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.

    • Pdf-extraction? Technically it is an interesting problem. But ... just stating the obvious ... you need to be careful with copyright. Make sure to clearly indicate the source of…

  • Problem difficulty or rating and filtering

    From 3 comments
    • It would be good to have the problems sorted according to difficulty or other user-defined criteria.
      zelphirkalt on HN
    • It would be really valuable to add a challenge rating to each problem. I am sure there are some criteria that could be used to auto score these. Then, viewers would be able to…

  • LaTeX support in comments

    From 2 comments
    • You wanted a thing, it didn't exist, and then you built it. Kudos to you! I don't know if part of the goal is to have a growing list of math problems and their solutions or not,…

    • Needs LaTeX support for comments

    • Pretty cool! You should make a section where users can submit problems. Of course they would need to be able to use latex too. They should also be required to write up a model…

  • Attribution of problem sources

    From 2 comments
    • 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…

Questions

  • Why is an account required to post a comment?

    From 2 comments
    • What is the account needed for? I assume you track progress, but are there other reasons for it?
      criddell on HN
    • But, why is it needed? To prevent spam?

    • a stackoverflow-like website for math already exists.[0] but i agree with the general sentiment of most people that the actual solution should somehow be easily accessible. i…
