This is cross-posted on my two blogs.
For my fans on either of my two blogs, I'm giving away a free signed copy of my new book, Numbersense. (See my book announcement.)
The contest is open until Friday, July 19, 2013 (11:59 PM PST).
This is an open anything quiz, although as I like to tell my students, if you are working too hard, you're probably missing the point.
I will draw the winner among those who answer all 3 questions correctly.
Please provide a valid email address so I can get in touch with you to send you the book.
