This article presents a novel method that allows to generalize the use of the Adam‐Bashforth to Partial Differential Equations with local and nonlocal operator. The Method derives a two step Adam‐Bashforth numerical scheme in Laplace space and the solution is taken back into the real space via inverse Laplace transform. The method yields a powerful numerical algorithm for fractional order derivative where the usually very difficult to manage summation in the numerical scheme disappears. Error Analysis of the method is also presented. Applications of the method and numerical simulations are presented on a wave–equation‐like, and on a fractional order diffusion equation.
