Tutorial

## Part I: Classifying a Matrix

Before we can begin to multiply matrices, we must first learn to classify them. In this video, you will learn how to classify matrices!

## Part 2: Undefined Products

Sometimes the products of two matrices is undefined. We can determine whether a product of two matrices is undefined simply by looking at the two matrices.

## Part 3: Classifying the Product

Using the classification of two matrices, students will be able to classify the product of the two matrices.

## Part 4: Multiplying Matrices

Multiplying Matrices: Students will be able to multiply two matrices using the dot product.
