Inspired by such illustrious compilations as the Canterbury Puzzles, Moscow Puzzles, and Tokyo Puzzles, Colombian mathematician and professor Bernardo Recaman Santos assembled these 80 brainteasers, which he acquired while living and working in Bogota. Santos's colleagues, students, friends, and acquaintances contributed to this stimulating collection, a potpourri of word problems, puzzles involving chess pieces, sudoku-style challenges, and other math-based diversions. Includes complete solutions. AUTHOR: Colombian mathematician and professor Bernardo Recamán Santos teaches students of all ages, from preschool to university. A devotee of Martin Gardner's books, he is a firm believer in the power of recreational mathematics to illuminate classroom teaching.
