Question

I need help with a Matrix question

Answer 1

do you know how to add matrices?

Answer 2

Not really :\

Answer 3

I want to learn how to do it though

Answer 4

well \(\large \begin{bmatrix}
a&b\\c&d
\end{bmatrix} +
\begin{bmatrix}
e&f\\g&h
\end{bmatrix}=
\begin{bmatrix}
a+e&b+f\\ c+g&d+h
\end{bmatrix}\)

Answer 5

as you can see is pretty straightforward, the same spot element, adds to the next "same spot" element on the other matrix, to get the "resultant" element

Answer 6

Ok that seems pretty simple

Answer 7

Is that how i would answer that question? Add them?

Answer 8

\(\large \qquad \qquad \qquad \qquad \qquad \qquad \qquad a\\
\begin{bmatrix}
4&7&8\\ 5&6&9 \\ 9&2&3
\end{bmatrix}+
\begin{bmatrix}
1&4&6\\ 3&9&2\\ 5&8&2
\end{bmatrix}=
\begin{bmatrix}
\square &\square &\square \\
\square &\square &{\color{red}{ a_{23}}} \\
\square &\square &\square \\
\end{bmatrix}
\\ \quad \\
a_{23}=\textit{on matrix "a", row 2, column 3}\)


so what do you think that is?

Answer 9

Oh! So that is what that means xD

\( a^{23}= 11\)

Answer 10

Right?
