Logic exercises for high school (1952)

This textbook is intended for tenth students of high school classes. In order to successfully learn the course of logic and learn to apply this knowledge in life, the student must perform a certain amount of logical exercises. For this, it is necessary that each student should make at least 15-20% of the exercises included in the real collection, or similar exercises in all sections of the course. It should be borne in mind that the successful performance of exercises by logic can be carried out only on condition that the content of the example is known and understandable to the student. Before solving a logical problem, you need to well understand the content of this problem. The best knowledge of logic cannot ensure the successful implementation of a logical exercise if the essence of the issue, which is discussed and an example, is not well understood by students
