    What on earth does K mean?

    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

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