\atop

## Description

\atop is the basic TeX command for stacking mathematical text. Printing

a\atop b


produces the stack ${\displaystyle a \atop b}$. Grouping may be required to make sure that not too much is included. A good rule of thumb is to simply put braces around any such stack as in

{a\atop b}
