    I have no idea what this means. "6" is a number. You can't "let" it be anything else!

    Okay, the matrix is
    [tex]\begin{bmatrix}1 & 1 \\ 1 & 0\end{bmatrix}[/tex]
    but what does "c" mean? The column space? That is just the space spanned by the columns as vectors, <1 1> and <1 0> which is all of R2. Surely, that is not what you mean. If it were "d" instead of "c", I might guess "determinant", which is normally abbreviated "det". That is, of course, -1.

    Now the matrix is
    [tex]\begin{bmatrix}0 & 1 \\ 1 & 0\end{bmatrix}[/tex]
    but I still don't know what "c" means.

    12? Surely that is not what you mean! Please explain your symbols.
