This book is addressed to students of the 3rd grade of the Unified Lyceum (general education), but also to fellow Mathematicians (given that it includes a large and original collection of exercises). It is written based on the new syllabus provided for this class. It includes the chapters Differential Calculus - Statistics - Probability .

In view of the fact that it is a General Education book, emphasis was placed on the comprehensible presentation of the relevant theory and on the presentation of a methodology, essential for the solution of the exercises.

Each paragraph of each chapter is accompanied by solved exercises.

At the end of the chapters there are solved application problems and questions to understand the relevant theory.
