How to solve a calcudoku

Fill the grid with 1 to N once in each row and column so every outlined cage combines by its operator to its target.

The method

1Read each cage. The small label is the target and the operator the cage must reach: a sum, difference, product or quotient of its cells.
2Start with single-cell cages. A cage of one cell is just that number given, so place it first and let it constrain its row and column.
3List the combinations. For a cage, work out which sets of digits reach its target, then cross off any that repeat a digit in a shared row or column.
4Cross cages with rows and columns. A digit must satisfy its cage and keep its row and column to 1 to N once each. Where only one option does both, lock it in.

The one rule: 1 to N once per row and column, and every cage hits its target.
What the answer page shows: The completed grid is printed at the back.
How the grades differ: Bigger grids and larger cages leave more combinations to weigh.
Good for: Solvers who like arithmetic with their logic.
