Text Formatting ⇒ \pm not showing as the +_ symbol

[peaches20]

Hi,

I have a couple of equations that have the +_ symbol and have coded the as \pm but it is typesetting as pm instead of +_ . Can anyone help with this -- am I using the wrong symbol. Below is my preamble and partial equation

Code: Select all

\documentclass[12pt,leqno]{article} 
\usepackage{amsmath, amsthm, amssymb}
\topmargin -.7in
\textheight 8in
\textwidth 6in
\oddsidemargin .25in
\evensidemargin .25in 
\parindent .15in
\everymath{\displaystyle}

\begin{equation}
f_{\pm} \pm 
\end{equation}

Thanks,
Peaches

Hi Peaches!

You showed good code, but it would be perfect to post a compilable minimal working example. Like this:

Code: Select all

\documentclass[12pt,leqno]{article} 
\usepackage{amsmath, amsthm, amssymb}
\topmargin -.7in
\textheight 8in
\textwidth 6in
\oddsidemargin .25in
\evensidemargin .25in 
\parindent .15in
\everymath{\displaystyle}
 
\begin{document}
\begin{equation}
f_{\pm} \pm 
\end{equation}
\end{document}

Now every reader can compile it or even open it by just one click in the online compiler Overleaf. When just a snippet ist posted, you may lose a dozen readers who don't make the effort to construct a complete document rom this.

With your code, I get:

pm.png (6.76 KiB) Viewed 3458 times

So I think, you make something different. What do you actually write?
