General ⇒ latex online - no centered equations

[blondecifi]

hope this would not be too much silly question..

I'm currently using latex online, is it possible to work with packages or any idea how to see whether they are already running or not ?

I'm trying to get an equation* not numbered, centered but without success.
I was reading about this example but it is not working

Code: Select all

\documentclass{article}
\usepackage{nccmath}
\begin{document}
\begin{fleqn}
    \begin{align*}
    a&=b\\
    &=c
    \end{align*}
\end{fleqn}
Which implies
    \begin{equation}
    a=c
    \end{equation}
But
\begin{fleqn}
    \[ 0\ne 5 \]
And
    \[ 2\ne 3 \]
\end{fleqn}
\end{document}

Thanks in advance for useful contents, happy 1st !

Your example does not contain any equation* environments.

[Stefan Kottwitz]

Simply use equation*, such as:

Code: Select all

\begin{equation*}
  a=c
\end{equation*}

Or shorter, \[ ... \]:

Code: Select all

\[
  a=c
\]

Your example above used a fleqn environment. fleqn stands for flushed left equations, that's why it's not centering.
