# How do you determine the order of the matrix [(33, 45), (-9,20)]?

$2 \times 2$

#### Explanation:

$\text{the order of as matrix tells us how many rows and columns it has}$

$\text{the order is written as } m \times n$

$\text{ where "m="the number of rows; }$

$\textcolor{w h i t e}{\times \times \times x} n = \text{ the number of columns}$

In this case we have $2 \text{ rows "2" columns}$

$\text{so the order is: } 2 \times 2$
