#### Abstract

In this paper, we study the ability of obtaining approximate analytical solutions corresponding to initial value problems associated with linear and nonlinear elliptic partial differential equations, by proposing the two-dimensional differential transformation method (DTM). The approximate solutions for these equations have the form of convergent power series. The tiny relative error occurs after few numbers of iterations shows that, the proposed technique is simple and convenient, revealing the efficiency and the high performance in reducing the size of computational work through obtaining the results. *Copyright © 2020 Praise Worthy Prize - All rights reserved.*
