Calculate the difference of the vectors \(\vec{a} = \begin{pmatrix} 1 \\ 5 \\ -2 \end{pmatrix}\) and \(\vec{b} = \begin{pmatrix} 3 \\ 2 \\ 4 \end{pmatrix}\).
\(\vec{a} - \vec{b} =\begin{pmatrix} \input{126606}{}{3em}{2em}{}{}\\ \input{226606}{}{3em}{2em}{}{}\\ \input{326606}{}{3em}{2em}{}{} \end{pmatrix} \)
