Found a wrong answer or a bug

Include the exact problem you typed (or a description of the image you uploaded), the answer you got, and what you expected instead. That's usually enough to reproduce and fix it quickly.

Requesting a new topic or guide

Tell us the topic, the grade level or course it's for, and, if you have one, an example problem. Topic requests directly shape what gets built next.

Everything else

Feedback, partnership questions, or anything that doesn't fit above is still welcome.
