Stage: 2, 3, 4 and 5

Ask NRICH is our 'Ask-a-Mathematician' service.

If you have a question about a particular problem (an NRICH problem or one you've seen somewhere else), or about mathematics in general, Ask NRICH is the place to go.

We have a team of mathematics undergraduates here at Cambridge University who will do their best to help you - not by giving you the answer but by helping you to think your way through the problem.
They are very quick and friendly!  - most questions get a useful reply within the day.

Anyone can read the posts on Ask NRICH but if you want to ask a question you have to register.

There are four main places to go:
