The international best-seller that makes mathematics a thrilling exploration
In twelve dreams, Robert, a boy who hates math, meets a Number Devil, who leads him to discover the amazing world of numbers: infinite numbers, prime numbers, Fibonacci numbers, numbers that magically appear in triangles, and numbers that expand without end. As we dream with him, we are taken further and further into mathematical theory, where ideas eventually take flight, until everyone--from those who fumble over fractions to those who solve complex equations in their heads--winds up marveling at what numbers can do. Hans Magnus Enzensberger is a true polymath, the kind of superb intellectual who loves thinking and marshals all of his charm and wit to share his passions with the world. In The Number Devil, he brings together the surreal logic of Alice in Wonderland and the existential geometry of Flatland with the kind of math everyone would love, if only they had a number devil to teach them.Binding Type: Paperback

Tough Bunny
Style: Bunny
So far so good. We’ve been able to play tug-of-war with it several times and it’s not ripped apart. That’s why I gave it 5 stars. My dog has big teeth and a strong body. So this bunny is tough
Only time will tell if it’s really worth the money

Hard to Destroy
Style: Bunny
My puppy hasn’t been able to destroy it yet. All other toys have only lasted about 10 minutes.

Favorite fetch
We have a 70 lb Aussie and a 13 lb Havanese who compete with each other to fetch toys. This hedgehog is their favorite, largely due to the loud assertive squeak. Our big dog is a chewer and has a history of getting to any squeaker in a toy, once nearly choking when successfully removing one from a smaller toy. She still tries to chew on this toy, going straight for the nose but has not yet gotten to the squeaker which is large enough that I don't believe would be a choking hazard if she did get to it. No soft toy is indestructible, but compared to other plush toys, this is more durable. Once the nose has been chewed off, I have simply hand stitched the hole closed and from then on she's no longer interested in chewing through it. Have run through the wash and comes out fine. When one eventually wears out I order a replacement and the 2 puppies compete once again over ownership.
