Easy Mathematical Puzzles With Solutions: CalcuDoku Puzzles – The Best Stress Relief Puzzles: 1 (Brain Games For Adults)

CalcuDoku is a mathematical and logical puzzle loosely similar to sudoku. It was invented by a Japanese mathematics teacher Tetsuya Miyamoto. The objective is to fill the grid in with the digits 1 through N (where N is the number of rows or columns in the grid) such that:
• Each row contains exactly one of each digit.
• Each column contains exactly one of each digit.
• Each bold-outlined group of cells (block) contains digits which achieve the specified result using the specified mathematical operation: addition (+), subtraction (-), multiplication (×), and division (÷).
• Unlike Killer Sudoku, digits may repeat within a block.
