Matrix inverses make sense - A simple condition for when the inverse exists

The video tutorial explains matrix inverses, focusing on left inverses and their conditions for existence. It discusses how left inverses undo matrix actions and the importance of not losing information. Examples illustrate these concepts, and methods to check for inverses are provided. The video concludes with a summary and homework assignments.
