How to put a symbol above another in LaTeX? [closed]
How to put a symbol above (on the head of) another? For example, I want to produce something like this in one line.
a
#
i.e., a above #.
The effect should be almost the same with $#^a$ except that a is on the top instead of top right of #.
Solution 1:
Use \overset{above}{main} in math mode. In your case, \overset{a}{\#}.
Solution 2:
If you're using # as an operator, consider defining a new operator for it:
\newcommand{\pound}{\operatornamewithlimits{\#}}
You can then write things like \pound_{n = 1}^N and get:
Solution 3:
${a \atop \#}$
or
${a \above 0pt \#}$
