Clean UI and useful resource for practising problems
From 3 comments
Love the very clean UI
gillyb on HNThis 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…
anonimo37 on HNThank 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…
calebkaiser on HNGreat 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.

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 HNThis 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…
icepat on HNI 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.

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…
ilikegreen on HNStrong 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.
bo1024 on HNPdf-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 HNIt 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…
dustfinger on HNGreat 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.

LaTeX support in 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,…

DeathArrow on HNPretty 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

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 HNBut, why is it needed? To prevent spam?

Note that the math stackexchange can also do this if searched correctly
belkarx on HNa 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…
