This book makes maths fun, even for those little people who believe it to be a laborious trudge through treacle. In fact, that would describe Robert, the main character in this book. He has been struggling with maths for as long as he can remember. One night, he dreams that he meets a little devil, The Number Devil, who teaches him, as he sleeps, all sorts of useful tricks with numbers.

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, whic ...more

He couldn't believe his eyes. This time his dream had come true! ...After he'd dressed, he took the chain off and stuck it in his pocket: he didn't want his mother asking silly questions. ...Where'd that star come from? she'd want to know the minute she saw it. Boys don't wear jewelry! ...How could he tell he

Robert, a boy who hates math and is frustrated because his teacher doesn't allow calculators, has strange dreams all the time. One night he dreams up a character called the Number Devil, who takes him away to a surreal world of numbers where Robert learns basic math concepts and a few handy shortcuts. After all, says the Numb ...more

It is aimed mainly to young teens,but is also enjoyable by adults that for some reason hate the maths or have a wrong concept of this field.

Is a tale where departing of elemental concepts as natural numbers,prime numbers,powers and square roots introduce more advanced concepts a ...more

My impression was that the book got the formula all wrong. The story is nonsensical and tedious, so you're ready to get to the math. The math is then explained via conversation between the main character and the number devil, so you really have to reflect on the topics after each chapter to understand them. ...more

Honestly, I don’t think this book will make you better at math, however it may help you understand some complex theoretical concepts, since it doesn’t focus in the applied mathematics, but rather in the pure theory behind them.

The narration is fantastic and creative, and in fact, pretty attractive. Besides, the pictures and dares really co ...more

It's cute, a math book for a young audience, and the beginning works well for me. However, it does become a bit tedious, especially since things are shown, not really explained and weird words are invented to do so. I now know why this didn't become a favorite of mine: you never quite learn wh ...more

If I was a child I would have loved this book, and I don't love maths. It was an intersting reading and I enjoeyed the things that you can learn while reading it. I think I'll recommend it to every kid (and not) who wants to read about math! ...more

What a truly novel idea for a novel. Absolutely extraordinary!

Although this is a book written for a young audience, I, as a 49 year old college student, found it both entertaining and instructional. In addition to a great story,
