Answer 1

Resposta:

$a)\begin{pmatrix}4&5\\ -1&2\end{pmatrix}+\begin{pmatrix}-2&3\\ -2&6\end{pmatrix}=\begin{pmatrix}2&8\\ -3&8\end{pmatrix}$

$b)\begin{pmatrix}4&5\\ -1&2\end{pmatrix}+\begin{pmatrix}-2&3\\ -2&6\end{pmatrix}+\begin{pmatrix}-4&-8\\ 7&10\end{pmatrix}=\begin{pmatrix}-2&0\\ 4&18\end{pmatrix}$

$c)\begin{pmatrix}-4&-8\\ 7&10\end{pmatrix}+\begin{pmatrix}1&0\\ -1&-3\end{pmatrix}=\begin{pmatrix}-3&-8\\ 6&7\end{pmatrix}$

$d)\begin{pmatrix}4&5\\ -1&2\end{pmatrix}-\begin{pmatrix}-2&3\\ -2&6\end{pmatrix}=\begin{pmatrix}6&2\\ 1&-4\end{pmatrix}$

$e)\begin{pmatrix}-4&-8\\ 7&10\end{pmatrix}-\begin{pmatrix}1&0\\ -1&-3\end{pmatrix}=\begin{pmatrix}-5&-8\\ 8&13\end{pmatrix}$

$f)\begin{pmatrix}-2&3\\ -2&6\end{pmatrix}-\begin{pmatrix}-4&-8\\ 7&10\end{pmatrix}=\begin{pmatrix}2&11\\ -9&-4\end{pmatrix}$
