It is well known that fuzzy numbers plays an important and fundamental role in fuzzy analysis. In this paper, we attempt to define the addition and scalar multiplication in fuzzy numbers using α-level set. We have first obtained some properties of interval numbers. From these properties we discuss some properties of fuzzy numbers.
