   The result's shape is neither triangular nor trapezoid. You need a   
   more generic subset of the fuzzy numbers, which would include the   
   shapes outlined by exponential functions, rather than only by linear   
   ones.   
      
   If you are working on a purely computational problem, I'd recomend you   
   to drop trapeziods, which are rather useless in computations involving   
   *, /, exp, and switch to nested rectangles   
   (http://www.dmitry-kazakov.de/ada/fuzzy.htm#1.4) or some other   
   representation supporting a richer set of arithmetical operations.
