I'd like to make \sum
and \prod
symbols slightly smaller than they usually are. There are several related questions, but none of them does exactly what I need. I do not want them to be as small as \scriptsize
or smaller; also, I want limits in textstyle and displaystyle to be as they originally are (that is, up and down in math mode; and next to $\sum$ and $\prod$ when inline). I have tried many things, but could not get what I desire. A (rather useless, I admit) MWE would be:
\documentclass{article}
\let\oldsum\sum
\renewcommand{\sum}{\oldsum}
\let\oldprod\prod
\renewcommand{\prod}{\oldprod}
\begin{document}
\begin{equation}
\sum \prod
\end{equation}
\end{document}
How could I resize sum and prod keeping the limits as they usually are? Thank you all in advance for your time.
