Matrix Multiplication

Author: Eric Bran
Description:
  1. Students will be able to classify the product of two matrices.
  2. Students will determine whether the product of two matrices is undefined or not.
  3. Students will be able to multiply two matrices of different classifications using the dot product of the elements. 

This tutorial is broken into 4 sections:

  1. Matrix Classification: Students will learn to classify matrices by counting the number of rows and columns.
  2. Undefined Products: Students will be able to determine whether the product of two matrices is defined or undefined.
  3. Classification of Products: Using the classification of two matrices, students will be able to classify the product of the two matrices. 
  4. Multiplying Matrices: Students will be able to multiply two matrices using the dot product.

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.
