I am curious about the proof of the fact that the value of a determinant computed using the Laplace (or cofactor) expansion is independent of along which row (or column) the expansion is performed.(adsbygoogle = window.adsbygoogle || []).push({});

Is this a very difficult proof? My textbook omits it entirely. I was curious if someone could provide a link to the proof, as I am interested in reading it. Wikipedia has a proof http://en.wikipedia.org/wiki/Laplace_expansion but it was too complicated for me to understand.

Does anyone know a simpler form of the proof i.e. one that is longer but clearer in its statements for a less insightful reader?
