Post Difficult 3 to -2 6x6 puzzle
I'm just now encountering the 1st bonus puzzle in memory that I've been unable to do. It is a 6x6 3 to -2 puzzle. 6 of the 14 operations are subtractions.

I'm afraid that I'm only computer semi-literate. Posting screen shots is beyond my skills.

I had a go at the puzzle and managed to solve it. I agree that the cages with minus operators are tricky, as the order in which you enter the numbers can change the result.

If you wish, I can post a full explanation of how I solved it. But the first few steps were to look at the possible numbers in column F, with F5 and F6 being 0 and 3 respectively. E5 and E6 can be either -1 and +2 or -2 and +1. One of these results in numbers in A6 and B6 that have too low a total, bearing in mind that each row and column must total 3.

If you get row 6 correct, the steps to solve the remainder of the puzzle are relatively straightforward.

paulv66, beaker and pnm,
Thank you for your encouragement and generosity. Unfortunately I was still not able to get over the hump. I guess I just have a block for this one.

I guess 3 to -2 6x6 bonus puzzles are on a roll. The one that I couldn't get was followed by another. Although I still didn't like it particularly, it was a lot less difficult than the previous one for me.
