Math & Science ⇒ how to lay the supscript exactly on the top of the symbol

[gcheer3]

Hello,
hope I can say this questin clearly. Thank you in advance!
I want to type 'N' exactly above the 'x' sign, and '1' exactly below the 'x' sign.
I tried the following code, the problem is that 'N' is towards the upper right corner of 'x' and '1' is towards the lower right corner of 'x'.

$\times_{1}^{N_1}\{0, 1\}$


I know I can use \limits if I want to sub- or super- script exactly below or above the sum sign, but it is in trouble for just a \times sign.

Use a combination of \overset and \underset which are provided by amsmath

Code: Select all

\documentclass[a4paper,11pt]{article}

\usepackage{amsmath}

\begin{document}

\[
\overset{N}{\underset{1}{\times}} \{0,1\}
\]

\end{document}

With amsmath you could also use:

Code: Select all

$\displaystyle\mathop{\times}_{1}^{N_1}\{0, 1\}$

The "\displaystyle" part would not be necessary in displayed math:

Code: Select all

\[ 
     \mathop{\times}_{1}^{N_1}\{0, 1\}
\]
