About calcudoku puzzles

Fill each row and column with the numbers 1 to the grid size, using each once. The number in the corner of a thick-lined cage tells you what the numbers inside must add up to, multiply to, or (on larger grids) subtract or divide to.

Every puzzle has exactly one solution. Smaller grids suit third graders, and the all-operations 5×5 grids challenge older students.
