Is it possible in a document to cancel the command \everymath{\displaystyle}?
It is in the macros.sty file I use but I would like to cancel it in some documents without changing my macros file.
[Tex/LaTex] Cancel \everymath{\displaystyle}

You could wrap the content in a varwidth environment, and use \Large to obtain larger text:
As mentioned in the comments \displaystyle should be used in math mode, So if you were using inline math $ ... $, the you could add \displaystyle as follows:
$\displaystyle {\mbi s} = {\mbi P}{\mbi d}, {\qquad{(2)}}\nonumber$
Code:
\documentclass{standalone}
\newcommand{\mbi}[1]{\textbf{\emph{#1}}}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx}
\usepackage{varwidth}
\begin{document}
\begin{varwidth}{\linewidth}
\Large
\begin{equation}
{\mbi s} = {\mbi P}{\mbi d}, {\qquad{(2)}}\nonumber
\end{equation}
\end{varwidth}
\end{document}
Then use array to adjust the style for the columns you're interested in:
\documentclass{article}
\usepackage{amsmath,array}
\begin{document}
\begin{enumerate}
\item \textbf{Limits}: Calculate the following limits
\begin{center}
\begin{tabular}{ *{3}{>{$\displaystyle}p{5cm}<{$}} }
\lim_{x \to -2} (x^2 + 5x) & \lim_{x \to 0} (x^2 + 3x - 4) & \lim_{x \to 2} (2x^2 + 5)^3 \\
\\
\lim_{x \to 0} \frac{x^2 - 2x -1}{x^5 - x^2 - 1 } & & \\
& \lim_{x \to 4} \frac{2x^{\frac{3}{2}} - \sqrt{x}}{x^2 - 15} & \lim_{x \to a} A x^n
\end{tabular}
\end{center}
\end{enumerate}
\begin{align*}
\lim_{x \to -2} (x^2 + 5x) &= \lim_{x \to -2} (x \cdot x) + \lim_{x \to -2} (5 \cdot x) \\
&= \left( \lim_{x \to -2} x \right) \left( \lim_{x \to -2} x \right) + \left( \lim_{x \to -2} 5 \right) \left( \lim_{x \to -2} x \right)
\end{align*}
\end{document}
Insert something before every entry in that column using >{<stuff>} and add something after every entry using <{<stuff>}.

\everymath{}should do it.
