Please enter the magnification of displayed formulae (formulae that appear on
a line by themselves.)  The normal value is 1, which makes the font size of
displayed formulae the same as the rest of the document.

If you enter a value that is a bit bigger than one, like 1.2, it will make the
fonts used in displayed formulae 20% bigger.  That might look a bit funny, but
small subscripts or superscripts will be more readable.
