In this book, multiple exercises on number theory are provided along with their solutions. We aim to cover all areas of this discipline. The primary objective of this book is to provide an accessible introduction to number theory, covering essential concepts, techniques, and theorems. Through a combination of examples and exercises, readers will develop a solid foundation in number theory and gain the necessary skills to solve problems and explore advanced topics. the difficulty level is indicated, ranging from easy to medium, difficult, and very difficult. The reader is given the freedom to choose the appropriate difficulty level from the 50 exercises presented in this first volume. The remaining 50 exercises will be presented in Volume 2. With both volumes, the reader will have a total of 100 number theory exercises, hence the title of the book.
