Is there a quick shortcut to find if a matrix (nxn) is singular or not?(adsbygoogle = window.adsbygoogle || []).push({});

For example, if the matrix is (2x2), and [tex]\Delta[/tex] (i.e. ad-bc) = 0, then matrx is singular and irrevertable..

Is there something similar for (nxn), like (3x3) and (100, 100), without doing the linear independence?
