近年来,初等数论在计算机科学、组合数学、密码学、代数编码、计算方法等领域得到了广泛的应用,同时近代数学中许多重要的思想、概念、方法与技巧都是从对整数性质的深入研究中不断丰富和发展起来的。因此,学习这门课程对学生来说非常重要,与其它数 In recent years, the elementary number theory has been widely used in the fields of computer science, combination mathematics, cryptography, algebraic coding and calculation methods. At the same time, many important ideas, concepts, methods and techniques in modern mathematics are all from the nature of integers Research continues to enrich and develop. Therefore, learning this course is very important for students, and other numbers
