I use the visual editor almost exclusively, and when I wish to write formulae in LaTeX, the fastest way I know is to type "<math", which opens the editor that hides most of the page. Once a formula has been entered, clicking on it brings up a "Quick Edit" box that doesn't hide the page and shows how the formula will appeared rendered inline. Is there a shortcut to bring up the quick edit box rapidly? Failing that, is there another way to enter TeX quickly short of editing source? ~~~~
In abstract algebra, the field of fractions of an integral domain is the smallest field in which it can be embedded.
The elements of the field of fractions of the integral domain are equivalence classes (see the construction below) written as
with
and
in
and
.
The field of fractions of is sometimes denoted by
or
.
Mathematicians refer to this construction as the field of fractions, fraction field, field of quotients, or quotient field. All four are in common usage. The expression "quotient field" may sometimes run the risk of confusion with the quotient of a ring by an ideal, which is a quite different concept.
