The whiteboard
Every solve opens on a real board.
Four ways to ask, one tap apart. Every solve opens on a whiteboard — the question rewritten in marker, your work marked, the fix highlighted, notes stuck to the side — and it is a real board: you can write on it.
Write on itApple Pencil on an iPad, a finger on a phone, a mouse on the web. The ink stays with the problem. Write your own attempt under the question and tap Check my writing.
Change the questionTap the question and edit it — a different number, a new part — then solve the new version right from the board.
Ask on the board“Why is that line wrong?” The answer lands on the board as a note, and in the chat too.
Pin anythingEvery note on a solve — the answer, why it works, the trap, one to try — has a pin. Pinned, it lands on your wall in its color, filed to its class.
