Unterstütze Lisa

Hi! I’m Lisa — a community college math professor, former AP Calculus teacher, and creator of XO Math on YouTube.

My goal is simple: Help students build confidence in math using clear, step-by-step video lessons - focusing on calculus and above.

I believe anyone can succeed in math with the right guidance and a little support. Every video I create is designed to break down tough topics in a calm, approachable way.

If my videos have helped you (or your students), you can support XO Math here.

Your contributions help me keep the video content free and create new resources like guided notes, practice problems, study sheets, and organized playlists.

Thanks for stopping by — and thank you for supporting accessible, high-quality math education 💙
