Matrix is an arrangement of numbers into rows and columns. Make your first introduction with matrices and learn about their dimensions and elements.

And as we develop an algebra around matrices, and when we talk about developing an algebra around matrices, we're going to talk about operations that we're going to perform on matrices that we would …

Learn what matrices are and about their various uses: solving systems of equations, transforming shapes and vectors, and representing real-world situations. Learn how to add, subtract, and multiply …

Khan Academy's Algebra 2 course is built to deliver a comprehensive, illuminating, engaging, and Common Core aligned experience!

Learn how to perform the matrix elementary row operations. These operations will allow us to solve complicated linear systems with (relatively) little hassle!

What you will learn in this lesson As long as the dimensions of two matrices are the same, we can add and subtract them much like we add and subtract numbers. Let's take a closer look!

Matrix multiplication is defined in such a way that it will be practically useful. This method is the most useful, hence it was adopted. You will see its applications in finding solutions of equations, among …

Matrices can be used to perform a wide variety of transformations on data, which makes them powerful tools in many real-world applications. For example, matrices are often used in computer graphics to …

The identity matrix plays a similar role in operations with matrices as the number 1 plays in operations with real numbers. Let's take a look.
