It's important to note that this book was first published in 1997 and you can tell. Robert the main character is 12 years old and was born in 1986 which is jarring in a 'modern' book.
The story elements are fine and the visuals are nice but considering this is a book marketed at children who struggle with maths and I am an adult who is confident with maths, the maths was very poorly explained and very often overcomplicated simple concepts.
In addition, some of the maths is now outdated and has been disproved although that is not the fault of the author.
The decision to use made up terms throughout the book and then include a disclaimer at the end is silly I think as most children will not read the disclaimer and will end up confused.
Finally there were a few fat phobic comments, there was racist images of Asian characters, and the description on the Bonacci sequence using rabbits suggested that all birth occurs through brother/sister incest which is confusing for children.

I think I bought this for my children but we never read it together so I reviewed it recently. It was fun and helpful and a good review.

I didn't mind the nicknames.

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.

I totally understand the concept of this book but if I had of actually looked through the book before buying it I don't think I would have brought it.
