1.3 Computation with Sage
In this section you learn how to use a computer to solve systems of equations for us. We need to know how to solve them by hand, but frequently in applications, you will need to solve larger systems.

Reading: Chapter 1 Section 1.3 from Understanding Linear Algebra, by David Austin.
In this section, we learn the very basics of working with SageMath, a free, open-source mathematics software program. If you are familiar with python, then this should feel comfortable.
There are Sage cells throughout our textbook, which you are encouraged to use. You can also access Sage cells here: Sage cells .
In video 1, we see how to enter matrices into Sage.
In video 2, we see an example of solving a system using Sage.
Here you’ll see an example of using Sage to solve an application problem with many equations:
