This book is written based on the curriculum of the school book and is structured in corresponding chapters, so that it operates parallelly and complementarily with it.

Each chapter contains tests with short-answer questions (true-false, multiple choice, matching, fill-in-the-blank). The aim of these tests is to assess and improve the student's ability to solve exercises and problems by applying basic mathematical knowledge and using observation and logical thinking.

It is very important for students to become particularly familiar with multiple-choice questions, as these are used in Mathematics Competitions.

At the end of the book, there is a brief presentation of the theory of each chapter. Each reference to mathematical concepts, rules, or definitions is accompanied by relevant examples for a more complete understanding of them. Additionally, the answers to the questions are provided, so the child is left with no questions or doubts.
