I recommend that you double-check your entry.

Yet another newbie question: I have a 3x3 matrix called V, filled with
numbers, whose output displays correctly. However, when I enter
Inverse[V] the output displayed is not the answer but the word Inverse
followed by the the argument matrix as Inverse[(elements of V)]. What
am I doing wrong? Gregory
