❖ Learn the RREF Steps and know how to determine if a matrix is in RREF or Not. RREF stands for “Reduced Row Echelon Form.”

❖ A basic introduction to the RREF and the steps of this elimination for matrices is presented in this precalculus tutorial. This method is a process used to solve a system of linear equations by converting a matrix into an RREF matrix by using elementary row operations and we have used different sizes of matrices.

❖ Gauss Jordan elimination is a process used to solve a system of linear equations by converting the system into an augmented matrix and using elementary row operations to convert a matrix into its RREF.
