# How to add text under symbol in equation ?

I was trying to make something like this

(something similar to \substack in \sum) in equation. How to do this ?

You should place the expression in the subscript, as shown below. Most LaTeX books explain this.

\documentclass{article}

\begin{document}

Display mode: $\max_{1 \leq j \leq n}$

Inline mode: $\max_{1 \leq j \leq n}$, $\max\limits_{1 \leq j \leq n}$.

\end{document}

Note how I used \limits to force the subscript under the operator in inline mode (if you think you need \limits, think again — maybe the defaults look better after all!).

If you find that the subscripted expression is too long and introduces excessive whitespace, use the \smashoperator macro from the mathtools package.

ah thanks, I thought it was limited to \sum command only. Silly me. –  Yumyai Mar 11 '11 at 10:07

Solved this for Inline mode by using $\underset{1 \leq j \leq n}{\max}$, however this approach requires the amsmath package.

$\max\limits_{1\leq j\leq n}$
