Elementary Number Theory 1st Edition by James K. Strayer (PDF)

Description

In this student-friendly text, Strayer presents all of the topics necessary for a first course in number theory. Additionally, chapters on primitive roots, Diophantine equations, and continued fractions allow instructors the flexibility to tailor the material to meet their own classroom needs. Each chapter concludes with seven Student Projects, one of which always involves programming a calculator or computer. All of the projects not only engage students in solving number-theoretical problems but also help familiarize them with the relevant mathematical literature.

User’s Reviews

Reviews from Amazon users which were colected at the time this book was published on the website:

⭐I bought this book for my Elementary Number Theory course and it is pretty much what you would expect. It covers the basic elements of number theory and gradually builds in a linear fashion. I feel like the questions are much more difficult than the proofs they give, but it’s made to be critically thought about; so, keep that in mind.

⭐Excellent book. I feel like it’s a great introduction to Number Theory (at least, at the undergraduate level, which is the class I took). Extremely straightforward to follow. The professor in my class did not teach particularly clearly, so I had to use the book for most of the learning. The exercises in each section are challenging but fun, and I like the longer projects at the end of each chapter, too.This book also contains what could be seen as an introduction to mathematical reasoning, such as proofing strategies. I think that this is the strongest aspect of this textbook. I never really was taught how to write proofs in my other maths classes (linear algebra, ODE, complex numbers), and I feel like this book is what finally taught me “how to math.” This textbook also doesn’t require much outside knowledge other than arithmetic and algebra, so I think it could be a cool transition to post-K12 mathematics.

⭐Purchased for class.

⭐I used this for a one semester undergraduate course. We covered the first 5 chapters. It’s pretty elementary, as can be seen by an appendix on the binomial theorem! But the exposition is very clear. Still it does require some mathematical maturity. Some of the problems are a challenge, but that’s the nature of the subject. The solutions are generally very simple once you get the right idea and the hints are very helpful. It also has a very high quality binding. For a first course it’s a very nice little book

⭐But this book does a decent job explaining it. I rented this and the person that rented it before left all there sarcastic notes written in it so it gave me a mild laugh while sitting through lecture.

⭐I had to get this textbook for one of my undergrad classes, and I was amazed by it. The book is definitely written for somebody new to the field, specifically college undergraduate level. However, my professor struggled explaining things a lot, and this book did a great job of making topics clear.

⭐Honestly don’t know how this book has less than 5 stars. Of all the similar titles I’ve gone through, this one is by far the most accessible and clear.

⭐It really good book in Number Theoery. It is easy to read and understandable . I recommended it
