# How to move the whole block of {align*} to the left?

I use {align*} a lot, it seems that the block of {align*} are automatically centered. How could I move the block to the left margin?

Use the flalign option to get left

\documentclass{article}
\usepackage{amsmath}

\begin{document}
\begin{align*}% this is centered
a &=b
\end{align*}
%
\begin{flalign*}
a &=b &% Need this tailing alignment char to get all the way left
\end{flalign*}
\end{document}

Cool... But I want some blocks to be on the left, some blocks to be in the center... –  SoftTimur Aug 9 '11 at 4:44
