Objective / Rules

• Complete the grid such that every row and column contains the numbers 1 to the size of the grid.
• Every row and column contains each number exactly once.
• A cage clue tells you the answer after the cage values have undergone the specified mathematical operation.
• The clues don't tell you which way round the numbers are, just the answer to the calculation.
• A number can appear more than once in a cage. Note: this is different to Killer Sudoku.
