A is a square matrix, I denote transpose A as A^T
The following statement is false:
"If AA is symmetric, then so is A. "
The counterexample is A= ((0 1) (0 0)), ie AA=((0 0) (0 0))

However, how to derive a counterexample for this question systemmatically?

One (1) is a whole number because one can be a whole, two (2) also could be, 3,4,5.... but why does zero (0) belong to the whole numbers even if zero doesn't represent a whole? there is no such thing as zero whole but rather there is 1,2,3,4,5,6,7....whole.....
