Here we will prove that the resulting matrix is unique; in other words, the resulting matrix in reduced row-echelon does not depend upon the particular sequence of elementary row operations or the order in which they were performed.

It turns out that they can be performed by left multiplying by certain invertible matrices. These matrices are the subject of this section.
