Sejam as matrizes

$ A = { \begin{pmatrix} -1\,\,\,\,0\\\,\,2\,\,\,\,\,\,\,1\\5\,\,\,-1 \end{pmatrix}}\,e\,B = { \begin{pmatrix} 2\,\,\,\,-1\\-1\,\,\,4\\0\,\,\,3 \end{pmatrix}} $

a operação A+2B resulta em:

!$ A = { \begin{pmatrix} 3\,\,\,\,-2\\\,\,-4\,\,\,\,\,\,\,\,\,7\\5\,\,\,\,\,\,\,\,\,5 \end{pmatrix}} !$

!$ A = { \begin{pmatrix} 3\,\,\,\,-2\\0\,\,\,\,\,\,\,9\\5\,\,\,\,\,\,\,\,-5 \end{pmatrix}} !$

!$ { \begin{pmatrix} -3\,\,\,\,-2\\\,\,0\,\,\,\,\,\,\,\,\,\,9\\5\,\,\,\,\,\,-5 \end{pmatrix}} !$

!$ { \begin{pmatrix} 3\,\,\,\,2\\\,\,4\,\,\,\,\,\,9\\5\,\,\,5 \end{pmatrix}} !$

!$ { \begin{pmatrix} -3\,\,\,\,-2\\\,\,4\,\,\,\,\,\,\,\,\,\,9\\5\,\,\,\,\,\,-5 \end{pmatrix}} !$
