Creating a fraction without the dividing line?
Arne
without the dividing line? Or are there other commands which do that?
Thanks

Now why would you want to do that? Combinatorics? Vectors? Well, you can
achieve a similar effect by using a 1x2 array:
\begin{array}{c}
1\\2
\end{array}

You can use the TeX primative \atop it is strongly discoraged because
of its bizare syntax ($a \atop b$). The best is the AMS \genfrac
command
\genfrac{Ldelim}{Rdelim}{rulethick}{style}{num}{denom}
with style:
Empty mathstyle arg: no change;
0 = displaystyle,
1 = textstyle,
2 = scriptstyle,
3 = scriptscriptstyle.
Usage: $\genfac{}{}{0pt}{}{a}{b}$

You can use \stackrel{text on top}{text below}, or $text\ on\ top
\atop text\ below$ (without the backslash, no blanks are set in the
output).

This depends on what you want that to mean. The amsmath package supplies
\binom{a}{b} which does what you ask and surrounds it with parentheses.
(there are also variants \dbinom and \tbinom to force a displaystyle
version or a text style (inline math) version.
For other constructs of a similar nature, amsmath also has a
\genfrac command.
If you are making a two-by-one matrix, there is
\begin{matrix}a\\b \end{matrix} (amsmath) or the array environment in
basic LaTeX
If you are creating a relation (e.g., by putting some symbol on top of
an equal sign) there is \stackrel (basic LaTeX).
If you are wanting to place a couple of lines under \sum, there is
\sum_{\substack{a\\b}} (amsmath).
Etc.
