Question
The image shows a matrix multiplication operation. 

On the top, there are two matrices. The first matrix, a 1x3 matrix, is shown in red and black:
\[
\left[ \begin{array}{ccc}
7 & 0 & -1 \\
\end{array} \right]
\]

The second matrix, a 3x1 matrix, is shown in blue and red:
\[
\left[ \begin{array}{c}
-4 \\
1 \\
7 \\
\end{array} \right]
\]

Below these, there is a 3x3 matrix filled with empty boxes, suggesting a place for the resulting elements of the matrix multiplication. Green arrows indicate the order of processing:
- Horizontal green arrows indicate the movement across the elements of the first matrix.
- Vertical green arrows indicate the movement down the elements of the second matrix.

The arrows imply the flow of operations necessary to compute the resulting matrix of the multiplication. Each element of the resulting matrix is typically obtained by taking the dot product of a row from the first matrix and a column from the second matrix.
