Question

The order of resultant matrix after multiplication

Answer 1

There are two types of multiplication for matrices: Scalar Multiplication and Matrix Multiplication. Scalar multiplication is easy. You take a regular number called a ‘scalar’ and multiply it with every entry on in the matrix. Let’s see an example:

A Matrix

Answer 2

Order of Matrix. If a matrix has M rows and N columns, the order of matrix is MxN. ... The number of rows and columns that a matrix has are called its order or its dimension and by convention, rows are listed first; and columns, second. So, the order of matrix A is 2 × 3 or you can say B is 4 × 3 matrix.
