I wished for a site with a growing list of math problems, I built it
Good math problems are hidden inside textbooks and online documents. To keep up with all the sources in the world is hard. For someone who just wants to continuously solve problems, finding and going through all the sources feels like a hassle. I wished for a website that could just dump all the math problems available in the world out there. And if I could filter the problems by topics, that would be beautiful. teachyourselfmath is a side project that was born out of this need. At its core, it is a math PDF extraction engine. The engine has some machine learning going on behind the scenes…

In plain words
Teachyourselfmath is a growing collection of math problems extracted from textbooks and online documents using machine learning. The platform uses an AI-powered PDF extraction engine to identify math problems in LaTeX format from images and documents, then organizes them by topic for easy browsing.

I made a web game that makes practicing basic arithmetic fun2024 · worchle.com · ▲161Hey, maker here. After launching a daily word search game, I randomly thought of this math game while driving. Finally got around to making it and I think it turned out pretty cool. It’s a math search game that’s meant to help you practice your quick addition, subtraction, multiplication, and division skills. I’m hoping it’ll help people (even those like me who aren’t big on math) learn and increase their speeds. (There are also some settings you can enable to make the game harder) If you try it out, please let me know if you found it fun, if you have anything you’d like me to add, or if you…
- IMI'm a teacher and built an AI presentation tool2025 · ▲260
Hi, I'm a high school teacher from Australia and I've built what I'd like to think is a pretty nifty ChatGPT powered presentation tool for teachers. I'd love it if you could have a look at it and give me some of your feedback. I don't think there's much overlap with the HN crowd and school teachers, but I've been coming here for many years and thought I'd post here and see what you all think. Check it out if you have a minute and I'd be super happy to hear your feedback too. https://www.slidehero.ai/ You can jump in and have a play with the tool all you like ;) Cheers, Eli



- HUHelp us curate the web’s best content for learning programming & design2012 · beta.whatispolymath.com · ▲49
Link here: http://beta.whatispolymath.com Despite all the educational material on the web, I found it pretty hard to learn how to code and design. I had trouble finding high-quality content, figuring out what to learn next, and staying motivated without easy ways to track my progress. So, my co-founder and I built Polymath. Our MVP is pretty simple right now: you can find & submit good content, bookmark & track your progress across different resources, and rate/comment on the material. We’re trying to build a really fun online learning community, and we’ve got some more cool features…
