Got a maths problem? Want to help Haiti? You're in the right place.

I'm trying to raise £1,000 for the DEC by helping a hundred people with their maths problems in exchange for a suggested donation of £10.

Here's how it works:
- you click here to e-mail me your question*.
- I tell you whether I can answer it**.
- You dig deep and donate £10 - or whatever you can afford.
- I get back to you with the answer.

I'm aiming for a 48-hour turnaround on questions, although that might change if I get behind. Sometimes it could be much faster :o)

Thanks!

Colin

** Up to A-level, I'm almost certainly OK. A lot of university level-stuff, too. But I can't find prime numbers of huge numbers or prove P=NP. Sorry.
