To explain the effect of the proposed procedure will be discussed three examples of the first, second and three-order linear mixed IDEs. The numerical results used to demonstrate the validity and applicability of comparisons of this method with the exact solution shown that the competence and accuracy of the present method.</p&gt;}, number={2}, journal={Earthline Journal of Mathematical Sciences}, author={Al-Humedi, Hameeda Oda and Shoushan, Ahsan Fayez}, year={2021}, month={Apr.}, pages={309-323} }
