Seeking a "magic square". Unfortunately, I have no picture, what I can tell, but I try to explain it this: You have a list with 6 * 6 boxes that are divided into several parts. In a box of this part is a number and either plus, minus, Shared or time (eg 3) is then you have to write to the other parts in each case the numbers that you can subtract and then what 3 results. the numbers from 1-6 may thereby appear only once in each row and column. I mean no Sudoku .. I hope someone can help me.
