New Alternative for Arithmetics Fuzzy Number

Abstract

: We will discuss about inverse of fuzzy matrix whose elements are fuzzy trapezoidal numbers. The discussion was prioritized from determining the new concept of positive and negative fuzzy numbers, namely by using the concept of broad positive areas. Based on the concept, there will be an alternative for multiplication concept will be discussed inverse fuzzy number matrix so that used directly to solve linear equation system of fully fuzzy trapezoidal.
