The book has been completely re-typeset for this edition, giving it a more attractive look, with more white space and with more of the formulas displayed. Even a proof of infinity of number of prime, the logic is puzzling. Try to learn and understand number theory at a comfortable level so that you can understand some of the least to most advance level topics found in this book. Did you know there are at least 200 prime numbers? The explanations are difficult to understand. The body of each chapter is essentially unchanged, except for the correction of some typos in the 5th edition and some footnotes pointing out now-inaccurate statements or obsolete terminology. A very good book with easy to understand proves. NZM has coverage of some newer topics not covered in HW, for example Schnirelmann density, factorization methods, and public key cryptography. However, they are there, in the worst places, causing me to scratch my head wondering "is this a typo?". However, the amount of typos is very unfortunate. Although this is well done, it has a very different character from the rest of the book: it is a survey, proving some results but quoting many. The exposition is very clear, and the proofs have just the right amount of detail: concise, but not too concise to follow. This book is itself 18 years old (the 5th edition was in 1991) but in many ways it is much more modern than Hardy & Wright. HW is deep rather than broad; it ignores many topics of elementary number theory, but goes into great detail on the ones it tackles. It is very readable, fairly free of errors (the ones that are there are easy to spot and do not cause confusion). Very nice book. I am an undergrad student in computer engineering. It would have been better if some of them were presented more analytically. The logic is clear and easy to follow. LibraryThing Review User Review - zaz360 - LibraryThing.

Introduction to the Theory of Numbers by Godfrey Harold Hardy is more sturdy than the other book by him that I had read recently. It is also significantly longer.

Updated in a seventh edition The Higher Arithmetic introduces concepts and theorems in a way that does not require the reader to have an in depth knowledge of the theory of numbers, but also touches upon matters of deep mathematical significance.

Reviews - An introduction to the theory of numbers (sixth edition), by G. H. Hardy and E. M. Wright. The book encompasses a vast array of number theoretical topics and is updated to include recent developments. The most conspicuous difference is that HW has no exercises; it is that peculiar thing, an introductory textbook aimed at mathematicians. But the typesetting introduced an alarming number of typographical errors: I counted 23 typos in this first printing, some serious, and I wasn't even looking very hard.
