Abstract
The formula available in the literature to find the sum of two discrete fuzzy numbers needs a major change. We have shown in this article with the help of numerical examples as to why the existing formula does not quite look logical. We are going to put forward a different formula to find the sum using the weighted average of the levels of presence of the discrete fuzzy numbers concerned. With numerical examples we have shown that our proposed formula does return expected results.
