Summary: Easy read, but good book....
Comment: Crossing the story Alice in Wonderland with a small, red, fiery-tempered devil with a passion for numbers gives you The Number Devil, a perfect tale with funny and curious characters.
Robert hates math, and he gets irritated because his math teacher doesn't allow calculators in class. In addition to that, he has peculiar dreams all the time. Then, one night, completely out of the blue, he dreams about a Number Devil, who takes him away to a fantastic world of numbers. Robert learns all about different mathematical ideas and concepts in a fun way. Over the course of 12 different nights, Robert learns about simple math ideas like factorials, fractions, the importance of zero, and the idea of infinity. But Robert's adventures don't stop there; Robert also learns about more complex things like triangle numbers, Fibonacci numbers, imaginary numbers, and irrational numbers. The Number Devil makes up funny terms in order to explain these to Robert. Square roots are called "rutabagas," prime numbers are "prima donnas," squaring becomes "number hopping," the Fibonacci sequence is called "the Bonacci numbers, " and factorials are named "vrooms."
Did you know that you can take any even number larger than two and find two prime numbers that add up to it? The Number Devil presents different mathematical ideas to Robert, using funny things like furry calculators and coconuts. Even Robert uses what he learns in his dreams in class. For example, the Number Devil uses coconuts to show Robert what triangular numbers are. He uses the coconuts to make triangles on the ground, and he comes up with the first ten triangular numbers: 1, 3, 6, 10, 15, 21, 28, 36, 45, and 55. Next, he comes up with a little rule for triangular numbers: Any number greater than 1 can be the sum of two or three triangle numbers. Try 83, for example. It is the sum of 10 + 28 + 45.
Not only does the Number Devil show Robert different math principles, but he takes him to Number Paradise, and there Robert meets different mathematicians like Carl Friedrich Gauss (of course, the Number Devil makes up names for the mathematicians as well, so Gauss is called Professor Horrors), Georg Cantor (Professor Singer), and Leonhard Euler (Owl). Robert also meets Felix Klein (Dr. Happy Little), and he sees the famous 'Klein Bottle' (the Little Bottle). The Number Devil shows how one can't tell the inside of this object from the outside!
I thought this book was very enjoyable and funny. The illustrations were amusing and the characters were hilarious. I especially liked the Number Devil himself. I would give the book an eight out of ten only because some of the concepts described were very elementary, and it became boring for me at times. Overall, I didn't learn a lot, but the little tidbits of information and the more complex ideas were interesting. I would recommend this book for all ages as a good read aloud or for a bedtime reading book. Happy reading!

Summary: The number devil
Comment: Well, this book was really interesting. It was alright to me, It was different from other books. This book talks about math more than any other books. It will teach you about something that you don't know anything about in math,and you will learn it easier if you do what he teaches you.
Well, not only does the book help with math,it has a lot of metephors. Well it has a lot of funny things in it. The book is really about Robet is having dreams aboout math and the The Number Devil is teaching him. He is learning things that he doesn't understand in school. Every night he has a dream, and it helps him every day he goes to school. At the end his teacher is amazed at what he can do. IF you read this book you will find out what happens.
Epiphany.
