This book was written with the aim of being a manual for the first grade of high school and not just another aid.

Like my previous books, it is addressed to:

• the demanding teacher who, as an educator, strives and worries about the best and comprehensive preparation of his students,
• ambitious and demanding students who seek the full range of phenomena and aim for solid foundations for their entire journey in high school, the national exams, and their future university studies.

The book includes:

• detailed theory,
• a multitude of applications, which is also the best methodology for solving exercises,
• auxiliary topics,
• multiple-choice questions,
• comprehension questions in the form of the second part of the exams,
• exercises and problems,
• evaluation criteria,
• answers to questions and problems.

The activities of the book (examples, questions, exercises, and problems) constitute a bank of topics with the maximum range, while their theory and methodology are the mechanisms of understanding and solving these topics.
