How can I typeset a big summation with index next to it (like that one in the photo below) instead of an index in the bottom ?! . I need help please :) .

The place (above/below or right) for the indices of large operators can be set explicitly using \limits or \nolimits:
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{align}
E &= \sum\nolimits_n f(x) \\
E &= 42
\end{align}
\end{document}

2This yields a small summation not a big one . Besides, I use align environment. – Hussein Eid Nov 07 '16 at 18:41
