WebIf r is a row operation and A a matrix we write r (A) for the result of applying r to A. Example 2.1 Let A be the matrix (1 2 3 4)(1 2 3 4). Then if r if r1 ↦ 2r2r1 ↦ 2r2, s is r1 ↔ r2 r1 ↔ r2, and t is r2 ↦ r2 − 3r2r2 ↦ r2 −3r2 , r(A) = (2 4 3 4) s(A) = (3 4 1 2) t(A) = (1 2 0 − 2). Lemma 2.2 All row operations are invertible.
