What is the determinant of a matrix? What does the determinant tell us about a matrix or the solutions to systems of equations? I’m this video we will use systems of equations to show where the determinant of a 2x2 matrix comes from. We will define singular and non singular matrices. We will then practice finding the determinant and using it to solve problems at advanced higher maths level.

0:00 - Defining the determinant of a 2x2 matrix using systems of equations.
