Rules:

The goal is to fill a grid with digits so that each column and each row contain the digits only once (a Latin square).
Additionally, the grid is divided into heavily outlined cages (groups of cells) and the numbers in the cells of each cage must produce a certain "target" number when combined using a specified mathematical operation (either addition, subtraction, multiplication or division).
Digits may be repeated within a cage as long as they are not in the same row or column.
