I am trying to type two or three lines using big parenthesis inserting some sentences. I am using this but it does not work for me.
\documentclass{12 pt}{article}
\begin{document}
\begin{eqnarray}
& & (product of (A\times_{c} B) by C)\nonumber\\
& &\times_{c} D) by E.
\end{eqnarray}
\end{document}
I want to use the parenthesis are big not the small usual one.
