WebInverse of a Matrix We write A-1 instead of 1 A because we don't divide by a matrix! And there are other similarities: When we multiply a number by its reciprocal we get 1: 8 × 1 8 = 1 When we multiply a matrix by its inverse we get the Identity Matrix (which is like "1" for matrices): A × A -1 = I Same thing when the inverse comes first: Web(AB)C = (AC)B. However, there are some matrices A, B, and C for which A(BC) equals (AC)B, for example A= B= C= I. That means to prove that this statement is false, I need to nd speci c matrices A, B, and Cfor which (AB)Cand (AC)Bboth exist, but do not equal each other. If I pick A= I, then all I need to do is nd two matrices Band Cfor which BC= CB. pa drivers license center clearfield pa
