math

Is there an equivalent of a Duolingo for intermediate/advanced Math?

Fan of burritos, digging into unutilized capacity,

trying to solve some problems at https://www.louiza.xyz

Best I've found so far is khan academy's calc and multivariable calc courses. I would love an app that just generated individual math problems at some selected difficulty and domain

Interested in ZK, FHE, PUFs, hardware, system design, ai safety, and smart contact security.

Ya same, particularly keen on an app with minimal friction that's conducive to building & maintaining momentum. 

Totally see how video's work for some folks but would prefer a more 'learn-by-doing' experience.

I would to, especially for math, I was mostly thinking about their quizzes. Still not exactly what I'm looking for from a math app though

I want to do just a few problems a day for a week or so after I learn something new to really solidify it in my brain
