I don't remember this really well as I read it as a kid, other than it was really cool and I think I had some crazy dreams after it. ( )

Bel libro per far avvicinare alla matematica tutti coloro che la detestano (come il sottoscritto). Direi che è adatto a tutti, anche ai grandi :) ( )

This is an adventure in mathematics. The book goes through different higher mathematical concepts that grow progressively more complicated. This work of fiction is interesting, because it uses the vehicle of a child being frustrated with his math teacher to start the story. The story is told through dreams and shows the magic and wonder of numbers. ( )

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. ( )

The reason we picked this book up was to help the kids see math as fun and interesting and this book certainly did the trick. It didn't tie in to anything we were learning because the concepts were quite advanced but it illustrated several ways numbers are just amazing and how they sometimes make perfect sense and other times don't. My husband, who is a numbers guys, found it intriguing as well. I think we will go back to this book again and again. ( )

Book description
Roberto è uno dei tanti ragazzi per i quali la matematica è un incubo incomprensibile. Una notte gli appare in sogno un curioso ometto rosso che gli propone straordinari giochi di prestigio: non con le carte, ma con i numeri. Per altre undici notti Roberto si addentra così nell'esplorazione dei sistemi numerici complessi, capisce sempre meglio le leggi e i meccanismi che li governano, incontra Pitagora e Archimede. Scoprirà che la matematica non è affatto la casa noiosa e un po' crudele che si studia a scuola, ma semmai un'avventura entusiasmante. Per Enzensberger la matematica è un mondo immaginario che riserva continue sorprese ed è capace di colpirti con la sua genialità. Questo libro, scritto per una bambina di dieci anni ma destinato ai lettori di tutte le età, ne è la prova.
Haiku summary

Amazon.com Amazon.com Review (ISBN 0805062998, Paperback)

Young Robert's dreams have taken a decided turn for the weird. Instead of falling down holes and such, he's visiting a bizarre magical land of number tricks with the number devil as his host. Starting at one and adding zero and all the rest of the numbers, Robert and the number devil use giant furry calculators, piles of coconuts, and endlessly scrolling paper to introduce basic concepts of numeracy, from interesting number sequences to exponents to matrices. Author Hans Magnus Enzensberger's dry humor and sense of wonder will keep you and your kids entranced while you learn (shhh!) mathematical principles. Who could resist the little red guy who calls prime numbers "prima donnas," irrational numbers "unreasonable," and roots "rutabagas"? Not that the number devil is without his devilish qualities. He loses his temper when Robert looks for the easy way out of a number puzzle or dismisses math as boring and useless. "What do you expect?" he asks. "I'm the number devil, not Santa Claus." (Ages 10 to adult) --Therese Littleton
