In this book you will learn to memorize numbers using your imaginative thinking, imagination, autobiographical memory, consciousness memory. When you play the next game, try not to look ahead, not to spy on the answer, otherwise the game will lose its meaning. Go to the next game if you coped with the previous one. For each game you will receive a certain number of points. Write them down. When you finish playing, add up the points and you will find out if your memory is good for numbers. Our students, Ira and Alyosha, will help you.
