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 appreciation for math, and also cherish the idea of having somewhere to find good exercises to tackle.

Not in the spirit of spoiling the fun or bring any unnecessary tension, I can't help asking: considering that these exercises are being scraped from .pdf sources, would you consider having the source for any given exercise? Of course, it brings problems of exposing possibly copyrighted material. I'm just wondering what your stance is on that.

Glad to hear this!

> Of course, it brings problems of exposing possibly copyrighted material. I'm just wondering what your stance is on that. Given that problems are anyway discussed on the internet in various forms, I wouldn’t see this as a copyright concern. And I intend to keep this list free. Aggregation shouldn’t be a problem, hopefully :)

I see. I still feel this must be carefully thought out, because although exercises are being discussed online, this platform could potentially outright distribute them all at once in a centralised manner. And it can be a source of tension, specially without attribution (I've grown a bit more sensitive to this issue after realising how much effort goes into producing good exercises, like Advent of Code for programmers).

I think there would be value in knowing a given exercise comes from chapter X of book Y; it might even help track knowledge dependencies, so to say (to solve exercise Z, student probably needs exposure to all chapters between X-3 and X). And it could also be possible to build thorough different levels of exercises in different areas: a set of basic computation exercises (invert this matrix; solve this simple integral) - and these exercises, as you probably know, can be generated easily; some intermediate exercises of theorem applications; and then groups of higher difficulty material (which are probably somewhat more creative exercises).

Anyway, this is really an inspiring project and I hope it brings you lots of joy! and, in case it helps anyone, I've found a good trove of mathematics resources over at https://math.libretexts.org/Bookshelves.

> And it can be a source of tension, specially without attribution understood, thanks for sharing your concern here. i agree with the general sentiment that coming up with good problems/content is a hard job. let me see what i can do.

> and these exercises, as you probably know, can be generated easily; Yes, this is on my todo list. To do problem generation instead of problem sourcing.

thank you for all the feedback!
