The happy hacking keyboard is my favorite and is made for programming https://hhkeyboard.us/

It has a pretty different compact layout and very nice keys that arent loud.

The closest thing you are asking for is https://projecteuler.net/. This isn't purely math and currently there isn't a good way for sites to analyze your proofs which is most of math. You could do previous Putnam problems or something similar and just manually check your solutions if you just want hard undergrad lvl problems, otherwise it's best to just get a textbook.
