Elastic scattering of positive and negative pions by nuclei has been analyzed by means of Glauber theory. The full multiple scattering series is calculated, including effects of the Coulomb interaction and inner Coulomb corrections. Double and quadruple charge exchange contributions to the elastic scattering differential cross sections are also included. Applications are made to scattering by ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ and ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$. Comparisons are made with measurements at 674 MeV.
