Finding Basis of 5x5 Matrix: A - A^T

[ND3G]

In a solution to an old exam the prof found a basis of a 5x5 matrix by simply subtracting the transpose of A from A aka(A - A^T) and then found the basis for the null for the now much simplified matrix.

Is that a general guideline I can follow? If so it would make my life a lot easier.
