All the maths community I found are either
- Chill/memes
- Homework help
Here I offer a community that do challenges not word riddles
- Anyone can post their own challenges.
- I will be posting daily to ensure a fresh stream of content will keep everyone entertained.
(This is a new community, if you enjoy maths, come help yourself.)
it is, but it’s iOS only. there’s also a music course.
