The lesson

He talks. The board draws. You type.

Turn your sound on — Mr. Cadabra explains every step out loud while the whiteboard draws it. When it's your turn, type your answer in the box and press Enter. Stuck? Use the Yes / No / I'm confused buttons, or ask for a 💡 Hint — he gives nudges, never just the answer.

And here's the secret: wrong answers are useful. Mr. Cadabra never makes you feel bad about one — he gets curious about it. That's how the learning happens.

The board never runs ahead of you — it waits for YOUR answer.

Your tools

Real math symbols, no hunting.

Need √, x², a fraction, or ≥? Tap 🧮 Math Keyboard next to the answer box. For exponents: type the base first, then the xⁿ key, then the power — so 2, xⁿ, 3 makes 2³. There's 📈 graph paper too: tap points onto the grid and send them straight to Mr. Cadabra.

Not sure how something works? Just ask him. "How do I use the graph paper?" is a completely normal question — he knows every button.
