Essential aid for every high school student
- Definitions of concepts
- Types and properties
- Basic methodology

This booklet, unique in Greek literature, will be useful to you during your studies in high school, as well as in your preparation for the national exams.
It contains the theoretical knowledge (definitions of concepts, types and properties) that you have learned in previous classes and should know for the continuation of your studies.
It also includes the basic methodology for solving exercises and problems, with representative examples.
My many years of experience as a mathematics teacher and author make me hope that this manual will contribute, even minimally, to your successful engagement with mathematics.
