Reseña del editor
Calcudoku has become a very popular puzzle. Solving one takes a combination of Sudoku-style logic reasoning and basic math skills, making it a much more interesting and satisfying puzzle. After the publication of "Calcudoku, 101 Advanced Puzzles" many people asked for more large Calcudoku puzzles. So this book has exactly that: 101 12x12 puzzles, and even one 15x15 puzzle. Variations include puzzles with a single operator, with zero, and with exponentiation.
