Summary: The operational approach to the Tau method is used for the numerical solution of a nonlinear Fredholm integro-differential equations and nonlinear ordinery differential equaions with initial or boundary conditions without linearizing. An efficient error estimation of the approximate solution is also introduced. Some examples are given to clarify the efficiency and high accuracy of the method.
