This book is to pure maths what Knuth's Art of Computer Programming is to computer science or Feynman's lectures are to physics. If I was to be a castaway on a desert island, and was permitted to take only one book on mathematics, this is the one I would choose. I cannot recomend it too highly.

This book is a classic, and deservedly so. It is comprehensive but not overloaded (like so many modern textbooks), crystal clear, well organized, rigorous. A wonderful text for teaching yourself higher math, which is how I am using it. But there is something beyond its didactic effectiveness that makes Hardy's work a must-have for anyone interested in math: This is a truly beautiful book, and working through it, while by no means easy, is an intellectual and aesthetic delight of the first order. Hardy is a genuinely elegant, subtle, incisive thinker, and his unbounded enthusiasm for his subject, duly controlled by British understatement, shines through every page. He conveys the irresistible, almost addictive quality of math.

We didn't know who Hardy was... I learned much later the great mathematician (and type) he was. This book is an introduction to calculus written by this great master. The treatment is very rigorous and the reading is pleasant because everything is clearly written and motivated. When I started I was good at college algebra but didn't have any idea of what a derivative is. Hardy taught me from these basic things up to uniform convergence, etc, in a remote island in southern Brazil. Well, I had Courant too, but this I found, at that time, rather difficult. Thousands of mathematicians started with Hardy. It would be a good thing for you to do it too.
