What happens when we try to find the inverse of a singular matrix?

In this video, we talk about what happens when we try to find the inverse of a singular matrix? Well, the inverse does not exist for a singular matrix. In this video, one approach to tell that the matrix is singular is to show that the determinant is 0. Another approach is to perform Gauss-Jordan Elimination, and we realize there is no way we can turn the matrix A into the identity matrix I. So, the inverse does not exist!
