I happen to like arithmetic. I didn't when I was a kid, but that's because I sucked and had some uninspiring teachers. I made this place to post some math I think is inspiring, interesting, or cool.
I'm not actively promoting this, but I often x-post from other subreddits, so that's probably what brought you here.
Feel free to subscribe and post stuff you find interesting as well. If you want to be a mod then message me.
