The teaching aid book you are holding contains:
- Detailed solutions to all exercises of the new textbook, with necessary reminders and methodologies included in the theory of previous grades and needed here. This is to ensure that there are no obstacles and gaps during your study.
- Criteria for self-evaluation for each unit separately, as well as collectively at the end of each chapter. These have been created with the sole purpose of knowing exactly what you need to know both for the written exams in June and to primarily acquire the foundations of mathematical knowledge that you will need in the future.
- Samples of competitions similar to those usually required in school written tests.
- Summary of the theory with emphasis on points that traditionally pose difficulties.
- Answers and indications of evaluation criteria, and finally
- Glossary of terms as well as useful internet addresses with activities and educational material that utilize new technologies.

This teaching aid aims to open the path of knowledge for mathematics and not to limit you to ready-made things and their simple use. [...]
