That's great to hear that you want to learn about matrices! A matrix is a rectangular array of numbers arranged in rows and columns. For example, a matrix with 2 rows and 3 columns looks like this:

$$\begin{bmatrix}
a_{11} & a_{12} & a_{13} \\
a_{21} & a_{22} & a_{23}
\end{bmatrix}$$

Matrices can be used for various applications, including solving systems of equations, transformations in geometry, and more. Would you like to start with some basic operations like addition, subtraction, or multiplication of
