Many mental arithmetic techniques have disappeared from modern schools, which is a shame! Calculators are now coming to the aid of students, and more and more children can no longer do mental arithmetic. Mental arithmetic develops logical thinking, memory, and mental flexibility, teaches the ability to see the essentials, teaches precision, and facilitates problem-solving. This book contains numerous problems created by the great 19th-century Russian mathematics teacher S. A. Rachinsky. The problems are simple in their formulation, but they provide excellent mental and arithmetic training. The unique illustrations immerse you in the atmosphere of old Russia. Solving problems with children in the evenings can not only be a great way to exercise the minds of both children and adults, but also a rewarding family tradition.
