This isn't a book about maths it's about numbers. It's another in the series of little hardback books that give you the interesting stuff from schooldays plus a bit more. So yes, some maths do appear but so do numerology, discussions about why certain numbers are lucky or unlucky in certain cultures, an entertaining round-up of film and book titles and popular phrases where numbers appear, explanations of the Golden Rectangle and the Fibonacci sequence that actually help the reader understand them, and a number of other short tours of the worlds of numbers.
I hated maths at school, I wasn't good at it and I never thought it would interest me. I got this book because I have others in the series and found them readable and informative, and with pleased surprise can report that this one is just as good.
