# About spacing between three identical symbols

The following code

 \documentclass{article}
\usepackage{amsmath}
\begin{document}
$*,**,***$
\end{document}


yields

What can be done in order to get rid of the different spacing when three consecutive identical symbols are used? (I only experienced this issue with the asterisk; maybe this behavior is exclusive of this symbol).

The problem is that TeX interprets the middle * as a binary operator in ***, so it adds more space. With one or two *'s this does not happen because binary operators need two operands.

To turn this "feature" off use {*}, which tells TeX to interpret the * as an ordinary character.

   \documentclass{article}
$*,**,*{*}*$

• +1, although it's a feature, not a "feature" ;-P – Rmano Sep 21 '16 at 11:31
