math-modesymbols
So I want to make the four elementary arithmetic symbols in math-mode, but I don't like the way the divison-symbol looks. I want it to look like you rotated the subtraction-symbol 45 degrees, and I find / looking too long.
I'd like it to look like the one on the bottom here. One way of doing it was by using \usepackage{graphicx} and inserting \rotatebox{45}{$\_\!\_\!\_$}, but this isn't very convenient and I was hoping there may be a better way of making this.
Thanks in advance.
I once proposed the following definitions
\newcommand\varpm{\mathbin{\vcenter{\hbox{%
\oalign{\hfil$\scriptstyle+$\hfil\cr
\noalign{\kern-.3ex}
$\scriptscriptstyle({-})$\cr}%
}}}}
\newcommand\varmp{\mathbin{\vcenter{\hbox{%
\oalign{$\scriptstyle({+})$\cr
\noalign{\kern-.3ex}
\hfil$\scriptscriptstyle-$\hfil\cr}%
}}}}
Example
\documentclass{article}
\newcommand\varpm{\mathbin{\vcenter{\hbox{%
\oalign{\hfil$\scriptstyle+$\hfil\cr
\noalign{\kern-.3ex}
$\scriptscriptstyle({-})$\cr}%
}}}}
\newcommand\varmp{\mathbin{\vcenter{\hbox{%
\oalign{$\scriptstyle({+})$\cr
\noalign{\kern-.3ex}
\hfil$\scriptscriptstyle-$\hfil\cr}%
}}}}
\begin{document}
$a\varpm b\varmp c$
\end{document}
\setminus should be what you are after.
\documentclass{article}
\usepackage{amssymb} % for \smallsetminus
\begin{document}
\[ \mbox{setminus: } A \setminus B,\quad \mbox{smallsetminus: } A \smallsetminus B, \quad \mbox{backslash: } A \backslash B\]
\end{document}
Note that you can find more information here on How to look up a symbol?. In particular, you have the Comprehensive LaTeX symbols and the website Detexify. There is also this post which was mentioned earlier in a comment
Best Answer
Detexify doesn't give any usable suggestions.
My best result was
\newcommand{\division}{\mkern-\medmuskip\rotatebox[origin=c]{45}{\scalebox{0.9}{$-$}}\mkern-\medmuskip}It gives you the same rounded corners as the default division line has.
edit: notice that this division in my opinion looks horrible for capital variables.
