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 (

Last example (

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
