At 4:00 the value in the bottom right of the matrix should be -3/2

A singular matrix is non-invertible! Your videos are great and we all really appreciate it, but please make sure to provide correct information. A student cramming will absorb everything you say without questioning it!

A singular matrix is not invertible and a nonsingular matrix is invertible.
