Inside every grid is a small, elegant arithmetic puzzle (also known as Calcudoku): fill each row and column with the numbers 1 to N without repeats, while the cells inside each outlined "cage" combine — using add, subtract, multiply, or divide — to hit its target. No guesswork. Just clean, deductive reasoning.
