Find the order of the matrix 𝐴.

𝐴 is equal to negative nine, six, negative three. The order of a matrix is its dimensions. The convention is to list the number of rows first and then the number of columns. The order of a matrix is written as the number of rows by the number of columns.

Matrix 𝐴 has only one row. So we write one for the first value in the order. Matrix 𝐴 has three columns. So we write three for the second value in the order.

We don’t evaluate this as a product. But we leave it in the form number of rows by number of columns. The order of the matrix 𝐴 is one by three.
