Subscripts

To get an expression, `exp`, to appear as a subscript, you just type
`_{exp}`.

Can be used only in math mode. Thus, for a simple expression that is part of the running text:

should display as "HH$_2$O is the formula for water

If a symbol has both subscripts and superscripts, the order doesn't matter.
The following are equivalent:

a_n^2anda^2_n

Subscripts are normally displayed in a smaller font; to prevent this and, for example, use a standard Roman font, one would use;

$J_{\rm Roman}$
