If you are, like I am, trying to get ready for university Maths by yourself, this is the book for you, easy to read, and the content is exactly what you need just after having taken a look back at the A level Maths (you will need at least to have another comprehensive book of A level maths at hand otherwise).
I thought twice about purchasing this book because the title makes it look like one of those "learn how to speak chinese in 15 days with no need to study". But this is not the case. It teaches you the basics of mathematical thinking so you are able to aproach a proof or a theorem with confidence, and above all, how to solve problems and study by yourself.
Also, I earn my living doing computer programming, and found that the book helped me quite a lot with my job as well. I now find myself thinking more logically and methodogically about any problem I come across, instead of rushing to type code and test.
Although it seems like a one day read when you receive it, it took me some 3 months to finnish it with about an hour a day. You have to do some research and be active with the learning (as the book will advice you to do), so it is not a book for a flight read.
I purchased "
A Concise Introduction to Pure Mathematics" at the same time I bought this, but found it too hard to follow at first. But after finnished How to Think... the Concise Intro... fits nicely and I find it far far easier to read now.
By the way, I am in Spain and planning to study here, but the book is as good for UK as for any other country as far as I can see.
