## Sudoku Variants Series (042) - Mathdoku

(Published on 16. September 2014, 00:00 by Richard)

For this Sudoku Variants Project I have planned to publish a different Sudoku variant every Tuesday. I will see how long it takes before I am running out of ideas.

Mathdoku
Place the digits from 1 tot 9 in every row, column and 3x3-block. The numbers in the grid are the results of binary operations (addition, subtraction, multiplication or division) of the digits on each side of the number. In each 3x3-block all the four binary operations have to be applied once.

Solution code: Row 2, followed by column 5.

Dabei sagst Du doch selber immer: "Wer lesen kann, ist klar im Vorteil!" ;-)

aaaaaaarghhh .... wie schwierig das ist wenn man den letzten Satz nicht liest! Und wie dusselig den letzten Satz nicht zu lesen, wenn man ihn doch selbst übersetzt hat! ;-)))))
