This document contains a summary of elementary row operations on matrices by Sunipa Bera. It introduces the three types of elementary row operations: interchanging rows, multiplying a row by a scalar, and adding a scalar multiple of one row to another. It explains that each operation can be performed by premultiplying the matrix by a elementary operator matrix derived from applying the operation to the identity matrix. Examples are provided to illustrate how to obtain the elementary operator matrix and use it to perform each type of elementary row operation on a given matrix.
