I just recently started doing UW contest math problems with my middle school aged kid— they're definitely not "core" material but are excellent for enrichment and building lateral thinking: https://cemc.uwaterloo.ca/contests/past_contests.html

Thanks a ton for sharing this. I have a kid in middle school and cannot wait to work few problems with him.

Have fun :) It's really nice how each contest has a pretty smooth difficulty climb across the 25 questions. The first ten questions are all very easy, but then after that it escalates a fair bit, so you can find the right window for you.

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…

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!

Amazing, thank you for taking the time to make the site :)

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 solution that could then be seen upon clicking a link.

Then, it would be very interesting how different users solve it in the comments. But it should be strictly about problems and solutions as to not turn into another mathoverflow.

Another suggestion would be to change the color scheme for accessibility reasons.

>At its core, it is a math PDF extraction engine. The engine has some machine learning going on behind the scenes to extract math problems in LaTeX from any image or document. I would like more to see curated hand picked math problems instead of mass imported problems from various sources. Along with solutions and detailed explanations and links to the theory needed to understand and solve the problem.

I think it could even be done by voting. Not voting for problems, but voting for the best solutions and explanations in the comments.

Handpicking best problem and writing detailed explanations could be quite hard for one person, but if a lot of people find someones explanation useful and insightful, and vote for it, then one person could handpick from roster of problems with good explanations.

That would also help platform by engaging visitors to not only learn math, but to teach the parts they know well to others. (I also found out that explaining math to others really helps you to understand it better, so win|win)
