In Openoffice.org, one gets into "equation mode" from the
"Insert -> Object -> Formula" menu selections
and can type in
x = bar A

There is a lot of elegance in the LaTeX style:
$x = \overline{A}$

As usual, it's not merely that things are "Bizarre and awkward", but
most often poorly documented. So it's good to share these sorts
of tips, we weren't born knowing these things.
