Notes

Can you complete the grid such that every row and column contains every number exactly once, whilst at the same time making sure the cage clues are satisfied? Very similar to Killer Sudoku except it's addition, subtraction, multiplication and division.

A cage clue tells you answer after the cage values have undergone the specified mathematical operation.
