To stay in touch with math, the annually publicized math problems from the German Abitur[0] are great! The problems are already separated into three difficulties, making it suitable to include in your website (although they might need translating).

this seems very interesting! thanks, i will check it out!

Are you interested in using https://vector-graph.com/ to add math diagrams? I created it exactly for this kind of websites and I'd be happy to waiver the fee for your site!

This looks really cool. Possible to connect with you to see how we can also use this for https://books.innings2.com/demo.

This is a free website for math content from grade 6-10th. This fits with our design philosophy. Want to see if we can make something interactive with vector-graph

Also consider https://cortexjs.io/mathlive/ in case you need LaTeX WYSIWYG ordinary people can understand

Nice work. Out of curiosity, how is the difficulty determined? I notice that some of the "hard" questions (inverting a 2x2 matrices or differentiating common functions) are much easier than others (proving that no natural number has Euler totient equal to 14).

hi! right now, it is manually assigned after parsing the problems. i am figuring out a relative system for assigning difficulty automatically.

I feel like the obvious answer is to let people vote on it, like an upvotes/downvotes system.

I remember when you first posted this and it is a project I think upon very frequently! It's nice to see you have made further progress — and that there are comments with attempts at solving! Great job.

I still find some problems with the navigation of the problems, but I am not even sure where to go to fix that. It has to do with the difficulty of each problem, but also with how large each topic is: algebra encompasses both linear algebra and linear equation solving, which is a very wide bracket.

But you're making progress. That's great! Congratulations on that, and I'll be sure to keep visiting the website.

Oh that looks cool! I have a static page with some math content, could use this!
