Matrix inverses are analogous to the multiplicative inverse (or reciprocal) in the number system. 
 
 
 
In the number system, the multiplicative inverse, if it exists, is unique. Indeed, the matrix inverse, if it exists, is also unique similarly, as shown in the following proposition. 
 
 
 
 
is invertible and its inverse is 
 
 
 
since 
 
 
 
(it implies that the matrix product in another order is also	by the invertible matrix theorem)
