Place the digits 1 to 9 in every row and column. The digits in each outlined group of cells, - often called "cages" -, must produce a certain "target" number in the top
left corner, when combined using the specified mathematical
operation (either addition, subtraction, multiplication or
division). Digits may be repeated within a given cage, as long as they are not in the same row or column.
This puzzle is also known very famously as KenKen or KenDoku. It is invented in 2004 by the Japanese math teacher Tetsuya Miyamoto, an innovator who says he practices "the art of teaching without teaching".
Solution code: Both diagonals, first the one from top left to the bottom right, then the one from top right to the bottom left.
