Is it possible to rotate a prime when you have a subscript too?

Question

So I want an apostrophe to denote the complement, but the ^\prime symbol looks a bit too angled.

I found somewhat of a solution here.

But I can't get it to work with subscripts, A_0^\prime yields:

But I want the prime sign rotated 12 degrees to the left. Is that possible?

Answer 1

With a slightly modified definition from the answer to "Create rotated prime symbol" (removing the trailing \;) it works.

\documentclass{article}
\usepackage[figuresright]{rotating}
\newcommand*{\p}{%
    {\mathchoice%
        {\turnbox{12}{$\displaystyle,'$}}%
        {\turnbox{12}{$\textstyle,'$}}%
        {\turnbox{12}{$\scriptstyle,'$}}%
        {\turnbox{12}{$\scriptscriptstyle,'$}}}%
}%
\begin{document}
$A\p_0$
\end{document}

Answer 2

\documentclass{book}
\usepackage{amsmath}
\begin{document}
    \begin{align}
              A_{0}^{\prime}
    \end{align} 
\end{document}

\documentclass{article}
\usepackage{rotating}
\newcommand{\pp}{\rotatebox{20}{\prime}}
\begin{document}
    $A^{\pp}$
\end{document}
