Ask a doubt, step by step

1Open the Solver tab (or Solve a doubt on Home).
2Pick the subject.
3Tap the camera button and take a clear, flat photo of one question. Or type it, using ∑ for equations, or hold the mic.
4Check the text Classy read from your photo and fix anything wrong, then send.
5Answer Classy's first step. Ask for a hint only when you're stuck.

Tip · One question per doubt. For a worksheet, send each question separately so Classy can walk you through each one.

Note · A photo that's too blurry or dark is rejected before it's read, so you can retake it straight away.

Hint mode

Solver doesn't hand you the answer. It breaks the problem into steps; you try each one, and Classy checks it before giving the next hint. A step tracker shows where you are.

You try first

Write the next step the way you would in your notebook.

Classy checks

Right? You move on. Not quite? You get a small nudge, not the answer.

You finish

When you reach the answer yourself, the full worked solution unlocks.
