In this paper, we introduce the definition of positive and negative fuzzy numbers based on the concept of area of fuzzy numbers on the right side of r-axis and the left side of r-axis (in the first quadrant and the second quadrant). From the concept of positive and negative fuzzy numbers, an alternative arithmetic for pentagonal fuzzy numbers is constructed. Then the multiplication form of pentagonal fuzzy numbers can be obtained in some cases. Finally, from the multiplication operations, it can later be applied to determine the multiplication identity and inverse of pentagonal fuzzy numbers.
