Number Systems: A Path into Rigorous Mathematics 2nd Edition, Kindle Edition

Number Systems: A Path into Rigorous Mathematics aims to introduce number systems to an undergraduate audience in a way that emphasises the importance of rigour, and with a focus on providing detailed but accessible explanations of theorems and their proofs.The book continually seeks to build upon students' intuitive ideas of how numbers and arithmetic work, and to guide them towards the means to embed this natural understanding into a more structured framework of understanding. The author’s motivation for writing this book is that most previous texts, which have complete coverage of the subject, have not provided the level of explanation needed for first-year students. On the other hand, those that do give good explanations tend to focus broadly on Foundations or Analysis and provide incomplete coverage of Number Systems.FeaturesApproachable for first year undergraduates, but still of interest to more advanced students and postgraduatesDoes not merely present definitions, theorems and proofs, but also motivates them in terms of intuitive knowledge and discusses methods of proofDraws attention to connections with other areas of mathematicsPlenty of exercises for students, both straightforward problems and more in-depth investigationsIntroduces many concepts that are required in more advanced topics in mathematicsNew to the second editionComplete solutions to all exercises, and hints for the in-depth investigationsExtensive changes to chapters 4 and 5, including defining integral domains as distinct from commutative rings, a more complete discussion of irreducibles, primes and unique factorisation, and more topics in elementary number theoryA completely revised chapter 8, giving a more coherent account of quadratic rings and their unique (or non-unique) factorisation propertiesA thorough correction of typos and errors across all chaptersUpdates to the bibliography Read more
