High School Math Solutions - Matrix Multiply Calculator, Matrix Scalar Multiplication

Last blog post, we talked about how to add and subtract matrices. Now, we will start getting into multiplication for matrices. There are two types: scalar multiplication and matrix multiplication. In this blog post, we will talk about the simpler of the two, scalar multiplication.

Scalar multiplication is when you multiply a matrix by a value, called a scalar. In scalar multiplication, you multiply each element of the matrix by the scalar.

Here is what scalar multiplication looks like:

Pretty simple, right? Now, let’s see some examples.

First example (click here):

1. Multiply each of the matrix elements by the scalar

2. Simplify

Next example (click here):

1. Multiply each of the matrix elements by the scalar

2. Simplify

Last example (click here):

1. Multiply each of the matrix elements by the scalar

2. Simplify

As you can see, scalar multiplication is pretty simple. In a later blog post, we will go over matrix multiplication. For more help or practice on this topic, go to Symbolab’s Practice.

Until next time,
