**Matrix Dimensions Exploration**

In this section, we will explore the dimensions of a given matrix.

Consider the matrix \([A]\):

\[ 
[A] = 
\begin{bmatrix} 
-5 & 5 & -1 & 10 \\ 
4 & 3 & 1 & -4 
\end{bmatrix} 
\]

To determine the size of matrix \([A]\), we need to count the number of rows and columns the matrix has. 

The matrix \([A]\) consists of:
- 2 rows
- 4 columns

Thus, the size of \([A]\) is determined as follows:

The size of \([A]\) = \_\_2\_\_ by \_\_4\_\_

This means that matrix \([A]\) is a 2x4 matrix. Each entry in the matrix is denoted by its position \((i, j)\), where \(i\) refers to the row number and \(j\) to the column number.
