k is just a variable here. They ask if you the matrix shown is elementary for all values of k.

Hi guys, I am a first year university student and busy with linear Algebra. Can anyone explain to me what on earth K is?
To give an example I saw some true and false exercises that say:
100
0k0 is an elementary matrix for all values of k.
001
and
k is any real number
I went through my textbook and google it but for some reason I just cant get an answer, can anyone please give some clarity on what k is?
Kind Regards
Hyperion
