The Channel 4 programme Countdown has started the search to find an arithmetician for the new series in 2009.

If you are a number-cruncher yourself, you could be just what they're looking for. Find out how to apply on their website. You don't have to be female and you don't have to have been on telly before, but you do need to have a way with numbers and lots of charisma. The closing date for applications is the 19th of September.
