It is organized into sections and fully covers the material of the school book: it follows the lessons - chapters that exist in the school manual and approaches each mathematical problem according to the new teaching guidelines.
In each chapter it includes:

- Detailed presentation of the theory in simple and understandable language. The work steps are presented while the assimilation of knowledge is achieved through the use of tables, diagrams, and relevant examples.
- Complete and detailed answers to all exercises and problems in the Student's Book and the Workbook.

At the end of each section, there is a test with review exercises covering the material of the entire section. With this test, the student has the opportunity to check their knowledge and prepare for the review examination at school.

It is followed by a glossary of mathematical concepts in which the concepts are listed alphabetically for the student to easily and quickly find their meaning.

At the end of the book, the answers to all the supplementary exercises and problems, as well as the exercises of the review tests, are provided.
