# How do you determine the order of the matrix [(-7, 6, 4), (0, -5, 1)]?

Order of the Matrix is given by $\left(2 , 3\right)$

#### Explanation:

Matrices are defined as a rectangular arrangement of numbers.

Since it is rectangular group(also known as an array), we can say that it is 2-dimensional.

The two dimensions here are the number of rows (m) and the number of columns (n) respectively.

Order of a Matrix tells us how many rows and columns are there in our Matrix.

If we call our Matrix $A ,$ and we have $\textcolor{red}{m}$ rows and $\textcolor{red}{n}$ columns then we can write our matrix $\textcolor{red}{A}$ as

$\textcolor{b l u e}{{A}_{m \times n}}$

In this case, Order of the Matrix is $\textcolor{b l u e}{\left(m \times n\right)}$

The given Matrix has ..

Rows = $2$

Columns = $3$

Hence,

Order of our Matrix is given by $\left(2 , 3\right)$
