### ⭐⭐⭐⭐⭐ 







  
  
    Very Good book on Number Theory
  

*by M***E on Reviewed in the United States on September 27, 2012*

Stillwell's book Elements of Number Theory presents a grand picture, starting with solving integer equations, and then working into general solutions of the Pell Equation. He covers basic ground, but without the generally random approach that most Number Theory books present.  In particular, he stresses repeatedly the importance of Unique Factorization, and in many ways his book is a build up to how Unique Factorization is "saved" in general algebraic structures by Prime Ideals. That by itself makes it worthwhile, because it is bringing in very important topics from Modern Algebra that are used in modern number theory. This is especially true because that angle is missing from several introductory texts on the subject (such as Dudley's classic text).  Great exercises, clear writing, and motivating discussion also gives the reader all important context. Too many number theory books show random results which, while pleasing, seem arbitrary. Here is a coherent development of deep ideas and a striking big picture. I am definitely glad to have it on my shelf.

I enjoy the algebraic approach to number theory.

    Wealth of ideas, beautifully presented
  

*by N***V on Reviewed in the United States on February 15, 2018*

After reading the first couple of chapters of Mr. Stillwell's book on number theory I've made plans to purchase his other college-level textbooks, including Elements of Algebra, Real Numbers, Four Pillars of Geometry, and, recently, Reverse Mathematics. I'm a mathematically-minded CS student and my interests fit very nicely with Mr. Stillwell's, plus I enjoy his style tremendously. Book is perfect for self-study.
