I'm giving away five signed copies of Numbers Rule Your World, and only people who read this blog are eligible.
All you need to do is to answer 5 questions. Click the quiz.
The contest is open till March 22, 2010 (12:00 AM PST).
I will draw 5 winners at random among those who answer all 5 questions correctly.
