In this paper some non linear arithmetic operations on triangular fuzzy numberspa,o,tm are discussed. Direct mathematical expressions to evaluate exponential, square root, logarithms, inverse exponential etc. of positive fuzzy numbers of type pa,o,tm are obtained using the basic analytical principles of algebraic mathematics and Taylor series expansion. The devised formulas are applied in various numerical examples that have an implementation scope in several engineering and real life systems.
