The negative-positive de nition triangular fuzzy number is expressed based on its geometrical area. The goal is to determine the arithmetic operation constructed on the result of multiplication of the triangular fuzzy numbers. Then the negative-positive triangular fuzzy numbers can be used to determine eigenvalues and eigenvectors of triangular fuzzy number matrices which refer to eigenvalues and eigenvectors of real matrixenFuzzy numbereigenvalues of fuzzy matrixeigenvectors of fuzzy matrixtriangular fuzzy numberArticle
