What people usually ask.

We do not promise that. What we do guarantee is how every result is handled: a computer algebra system (CAS) checks it on the server. If the check fails, the answer is marked unverified or withheld. The explanation in words is written by a language model; if something looks wrong, tell us.

A-level and first-year university maths: calculus, linear algebra, geometry in space. It also helps with exam preparation.

Usually about a minute. The result is computed, checked and the board is built before you see it.

A 2D or 3D figure that goes with the explanation. Each step draws or highlights something; 3D scenes rotate and zoom.

No. It is a resource for understanding one problem step by step, at home or in class.
