Features: This book is one of four paperback collections of brain-teasing puzzles translated by the author himself. These four books were published in Paris in 1973 and became wildly popular in France and Italy. This collection focuses solely on numerical puzzles, while the other three cover geometry, logic, and letter-based problems. Denis Dugas, the artist who illustrated these four books, is an old friend of the author. The puzzles in this collection have all been carefully selected or meticulously designed (many of them are original creations by the author or the illustrator), ensuring that none are too difficult for ordinary readers who are not mathematicians, yet none are too easy either. The problems are stated clearly and concisely, with accurate answers provided at the end of the book. Whether you solve them or not, the process will be filled with much enjoyment. Currently, Berlokan and his wife Annie, along with their two children, reside in Neuilly-sur-Seine, a suburb of Paris.
