Question

[4 5 ] +2 [1 8]
[0 -1] [-4 -6]

[-3 3] - [2 6 ]
[5 9] [-5 11]

-0.5[10 8]
[-2 -6]

can someone simplify these?

Answer 1

I'll do the first one to get you started


\[\Large \begin{bmatrix}
4 & 5\\
0 & -1
\end{bmatrix}
+2
\begin{bmatrix}
1 & 8\\
-4 & -6
\end{bmatrix}\]



\[\Large \begin{bmatrix}
4 & 5\\
0 & -1
\end{bmatrix}
+
\begin{bmatrix}
2*1 & 2*8\\
2*(-4) & 2*(-6)
\end{bmatrix}\]



\[\Large \begin{bmatrix}
4 & 5\\
0 & -1
\end{bmatrix}
+
\begin{bmatrix}
2 & 16\\
-8 & -12
\end{bmatrix}\]



\[\Large \begin{bmatrix}
4+2 & 5+16\\
0+(-8) & -1+(-12)
\end{bmatrix}\]



\[\Large \begin{bmatrix}
6 & 21\\
-8 & -13
\end{bmatrix}\]


So \[\Large \begin{bmatrix}
4 & 5\\
0 & -1
\end{bmatrix}
+2
\begin{bmatrix}
1 & 8\\
-4 & -6
\end{bmatrix}
=
\begin{bmatrix}
6 & 21\\
-8 & -13
\end{bmatrix}
\]
