Is it Possible? (Posted on 2024-09-06) Difficulty: 2 of 5
Is it possible to create a 3 x 3 matrix, using only the numbers -1, 0, and 1 such that all six row and column sums are distinct?

This proof is not complete, Jer.  It fails to rule out sums of -2,-1,0,1,2,3, where 3 and -2 are both row sums.
