# Multiply a Matrix by a Number Worksheets

How to Multiply a Matrix by a Number - Matrix multiplication can be a difficult process to master. However, multiplying matrices by a number of any other element can be a pretty easy thing to do. Unlike matrix multiplication, while multiplying an external number with the internal elements of a matrices, you just have to simply multiply the external number with each of the individual internal elements of the matrix. For example, if a 2 x 2 matrix has 1,2,3, and 4 as its elements and you want to multiply the number 5 by all its internal elements, then the process is simple. You just have to multiply the number 5 by every internal element of that matrix individually. 1 will become 5, 2 will become 10, 3 will become 15, and 4 will become 20 in this case.

• ### Basic Lesson

Guides students through determining the product of matrix and a number. Let A=[aij] be an m X n matrix and k be any number called scalar. Then the matrix obtained by multiplying every element of A by k and is denoted by kA. Therefore, kA = [kAij] m X n
