Actuarial & Annuity notation in LaTeX
Jeffrey C. Liter
look like the following:
A __
x:n|
where the expression x:n is a subscript to the A. The bar over the
expression x:n should connect to the vertical line following the n,
forming a right angle. The length of the angle should change with the
length of the expression it encloses, as would a square root symbol.
Any help would be greatly appreciated.

$A\annu{x:n}$

The array stuff isn't really necessary, but it is just the "obvious"
way to add rules to things.
\def\annu#1{_{%
\vbox{\hrule height .2pt
\kern 1pt
\hbox{$\scriptstyle {#1}\kern 1pt$}%
}\kern-.05pt
\vrule width .2pt
}}
Tweak ".2pt" and "1pt" for appearance.
