    To add the matrices add corresponding elements so:

    <br />
\left[ \begin{array}{ccc}<br />
{3}& {2}&{1}\\<br />
{4}& {0}&{1}<br />
\end{array} \right]+<br />
\left[ \begin{array}{ccc}<br />
{2}& {-3}&{5}\\<br />
{1}& {7}&{6}<br />
\end{array} \right]=<br />
\left[ \begin{array}{ccc}<br />
{5}& {-1}&{6}\\<br />
{5}& {7}&{7}<br />
\end{array} \right]<br />
,

    yes your answer is right.
