Dear student,
The book you hold in your hands can become a valuable tool for knowledge, understanding, and mastery of the mathematics of the 2nd Grade of Gymnasium. Your study must necessarily be divided into three stages:
-THEORY
Knowledge of theory is a fundamental part of studying mathematics. Learn, understand, and master the theory presented at the beginning of each unit. The presence of many examples will help you.
-TYPES OF EXERCISES - SOLVED APPLICATIONS
Once the theory has truly become your own, study and understand the various types of exercises you will encounter. The solved applications corresponding to the different types of exercises will assist you in this. Solve and re-solve the solved applications so that you fully understand how and why everything is done. Do not try to memorize exercises!!! Mathematics is about thinking and logic, not rote learning.
-CLOSED-TYPE QUESTIONS - EXERCISES TO SOLVE
Once the previous two steps are completed, solve the closed-type questions at the end of each unit. Then solve the exercises to be solved without any help. Try as much as possible to tackle the difficult points. If the solution does not emerge, there are hints-answers at the end of the guide to help you or to check the results you found.
Do not forget that these steps are essential to fully understand what each unit deals with.
When the exam time approaches, use the "REVISION GUIDE" available in the book. The theory questions will help you see if you know the theory, the revision exercises to check your ability to solve exercises, and the indicative exam topics to give you an idea of the logic of the final exam.
I would like to thank my colleague Maria Efstathiou for her contribution to the writing of the first guide for the mathematics of the 2nd Grade of Gymnasium, part of which is also used in this guide.
