《数论概论(英文版.第4版)》面向非数学专业学生，讲述了有关数论的知识，教给他们如何用数学方法思考问题，同时介绍了目前数论研究的某些前沿课题。本书采用轻松的写作风格，引领读者进入美妙的数论世界，不断激发读者的好奇心，并通过一些精心设计的练习来培养读者的探索精神与创新能力。对于定理的证明，则强调证明方法而不仅仅是得到特定的结果。
与第3版相比，本版的具体更新如下：
新增一章，详细介绍数学归纳法（第26章）。
前言部分给出了各章之间依赖关系的流程图，便于读者选择阅读。
调整了内容的组织结构，将反证法的相关材料前移至第8章，原根的相关章节移至二次互反律与平方和之后，上一版第47~50章的内容移至网上。
给出了二次互反律的完整证明，以及雅可比符号二次互反律的部分证明。
更新了书中的实例及章后练习题。
