Post 23 Dec 2019 Difficult 7x7
This puzzle has two cells with the calculation result 1^
The only ways I know to get that result of 1 are 1^1 or any number raised ^0.
But there isn't a 0 (its 1-7), and I can't put two 1s in the same column.

So I am mystified...

1^x = 1 [wink]

(with x integer and >= -1 I think)
