Description 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 . 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 it to them.
Insightful reviews Bradman: Great book. It talks about maths in a way that is as simple as 1+1=2. I was way behind in maths going into high school, and I have learnt so much from this book in 1-2 months. I learnt stuff like Fractions, Bonacci/Fibonacci numbers, Decimals, Factorial (Vroom!), Hopping numbers, Prima Donnas, and Triangle numbers. My favorite was the "Hopping Numbers". I spent a good part of a day just writing them all down. I wrote down 55 hopping numbers, and the biggest one I did was 18,014,398,509,481,984, which was too big for my calculator to check. "All Englishmen are liars," the man mumbled, "but if I say it, what then? I'm an Englishman myself. so I'm lying too. But then what I've just said - namely, that all Englishmen are liars - is not true. but if Englishmen tell the truth, then what I said before must be true as well. In other words, we are liars." A must read book. :D

Francine: I really liked this book (and learned a lot from it!) and I really hate math. I mean, really. I have a real fear of numbers, and this book felt good. Kelly H. (Maybedog): Random math thinly disguised as a novel. I get what it's trying to do but it feels more like the kind of characters that kids' textbooks have to make the info more "fun." there isn't a plot here. But if it gets kid's reading about math then go go go. Plus, the illustrations are really cute.

Raka Nouvel: Melihat judulnya sempat terpikir bahwa ini semacam fiksi horor.Horor? Ya, dengan warna merah yang bernuansa seperti darah, conceal dengan judul Setan Angka ini memang sempat membuatku berpikir, "Is horor fiction?"Fiksi? that is true, yet horror, completely NOT.Hans Magnus menulis sebuah cerita fiksi tentang matematika. Ya, tentang hal yang kata sebagian orang merupakan pelajaran yang menyebalkan. Rupanya Hans ingin mengajak anakanak di seluruh dunia yang tidak menyukai matematika menikmati petualangan si tokoh utama dalam buku ini.Petualangan tentang matematika. Hmm, sounds boring.Bagaimana mungkin anak yang tidak menyukai matematika jadi tertarik dengan hal tersebut? Hanya dalam sebuah cerita? Yeah.Bisa. Tentu saja bisa.Pertama, mereka akan menyukai ide ceritanya. Cara Hans bercerita sangatlah mengalir dan deras. Begitu derasnya seperti air terjun niagara. Sehingga pembacanya tidak akan menyangka kalau mereka sedang mempelajari matematika. Ya, belajar! Membaca buku ini berarti belajar.Kedua, seting cerita ini sangat manusiawi. Sangat sehari-hari dimana si tokoh utama adalah seorang bocah lelaki yang 'tidak terlalu suka' matematika, yet he has a great curiosity. Dan di dalam dunianya yang manusia, setan angka muncul dengan sangat manusiawi. Di dalam mimpi. hm, benar-benar manusiawi. Karena di dalam mimpi kita bisa bertemu setan apa saja, termasuk setan angka. Hal ini tidak membuat ceritanya berkesan fantasi yang dibuat-buat. But, math is math. Mau tidak mau, Hans sepertinya terjebak untuk menjelaskan sesuatu yang 'mulai rumit' di tengah cerita. Ada begitu banyak aplikasi matematika yang dilakukan si tokoh utama. Menjumlah, mengurangkan, mengali, membagi, memangkatkan, mencari akar, sampai pada konsep-konsep matematika yang 'tidak lagi sederhana'.Tapi tenang saja. Hans adalah penulis andal dan pecerita yang ulung. Dia tidak akan membiarkan kita sebagai pembacanya diam dan merenung dengan perkara matematika yang ditulisnya. Maka dia dengan sengaja membuat cerita yang bernada, "Come on, ignore fixing the problem. Just, benefit from the story!". Jadi meskipun ada banyak angka dan operasi hitungnya takkan membuat pembaca (yang sasarannya adalah anak-anak
anti matematika) menghentikan cerita di tengah jalan dan menjadikan buku setebal 270an halaman ini lamentably tidur. Tidak, Hans sudah mengantisipasinya.Saya hanya membaca buku ini dalam waktu satu hari. Apakah sesingkat itu? Tidak. Sebenarnya sama sekali tidak singkat.Yang saya lakukan adalah membaca bab pertama, terpukau dengan paragraf-paragraf awalnya, terkesima dengan ilustrasinya yang khas, dan saya memutuskan untuk membacanya sampai akhir. Di hari yang sama. Saya seperti tersihir oleh si setan angka untuk menyelesaikannya dalam satu hari. Saya sangat suka buku ini. Personally, when you consider that i like math and i am a math teacher. yet ahead of now, i used to be a child who do not like math. So i am yes sufficient this publication can switch lil bit the reader's brain approximately math.You do not like math? otherwise you are a math lover?Whatever! Oh, come on. Just, benefit from the story!Really, i like to recommend this book. Shaima Mannan: The quantity satan i might supply this e-book four stars simply because it is a nice e-book that is very educational. i believe it might be nice for a long time 10-12. It particularly takes the subject of math and algebra and makes into anything extra fascinating and informative on the related time. This ebook is a piece corny,to be sincere it truly is kind of infantile yet that is what i discovered to make this ebook very interesting. it really is a couple of boy who's having those nightmare's approximately math and this "number devil" appears to be like and attempts to assist him although he himself had difficulties to deal with. They cross on and experience to benefit new issues on math. it truly is fascinating and also you get to work out the characters type of switch and also you get to appreciate them more. This publication covers many themes on math very in short and will be important to people who are younger and do not quite take pleasure in math as much. it is stress-free to work out the humorous discussion among the 2 characters yet but occasionally issues within the tale are symbols to a normal proposal and lifestyles which are very relatable. total i feel this ebook is a light-hearted, humorous and kind of nonsensical publication that's nice to learn when you've got no different ebook to learn and when you are bored.
