This paper present a new concept arithmetic of triangular fuzzy number, namely by using a board area concept of triangular fuzzy number, so that we will get a form multiplication of fuzzy numbers in some cases. This new arithmetic concept will be applied for solve the fully fuzzy linear system using inverse matrix. Furthermore, to illustration will given numerical examples of solving fully fuzzy linear system using inverse matrix with a case of multiplication positive fuzzy number and negative fuzzy number.
