Brace terms in Tex
Code
In TeX, when indicating the number of terms, the \overbrace
and \underbrace
commands are commonly used to group multiple terms. To use these two commands, you need to load the amsmath
package via \usepackage{amsmath}
.
\documentclass{article}
\usepackage{amsmath}
\begin{document}
$$
x + n = x + \overbrace{1 + \cdots + 1}^{n \text{ times}}
$$
$$
xn = \underbrace{x + \cdots + x}_{n \text{ times}}
$$
\end{document}
Both commands take the formula to be grouped as the first argument, and how it will be grouped as the second argument. Note that \overbrace
is preceded by a caret ^
for the second argument, while \underbrace
is preceded by an underscore _
