Answer 2

An m x n matrix is an array of numbers (or polynomials, or any functions, or elements of any algebraic structure) with m rows and n columns.

When we describe a matrix by its dimensions, we report its number of rows first, then the number of columns. A 2x3 matrix has 2 rows and 3 columns. There are six elements in the matrix.
