RREF example for \(2 \times 2\) and \(3 \times 3\) matrices which we took them from the video “Determine if matrices are in RREF with steps” which is in this playlist.

❖ Do RREF for simple matrices, so we have transformed the matrix to Reduced Row Echelon Form. The sizes of the matrices we have chosen for this video are \(2 \times 2\) and \(3 \times 3\) matrices. The size of matrices is sometimes called order or dimension.

❖ A basic introduction into the reduced row echelon form 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 a reduced row echelon form matrix by using elementary row operations and we have used different sizes of matrices.
