Abstract: In this paper, we consider the following problems: 1. “Let à is a fuzzy number and x a real number. Then, what do we say about whether x is greater (smaller) than or equal to Ã?”. 2. “Let à and $\tilde{B}$ are two fuzzy numbers. Then, what do we say about whether $\tilde{B}$ is greater (smaller) than or equal to Ã?”.
