Eliasi and Taeri [M. Eliasi and B. Taeri, Four new sums of graphs and their Wiener indices, Discrete Appl. Math., {\bf 157} (2009), 794-803] presented four new sums and computed their Wiener index. In this paper, we continue this work to compute the Zagreb, Hyper-Wiener and Degree-Distance Indices of these graph operations. Some applications are also presented.
