Math & Science ⇒ Left Alignment for long Equations

[pemfir]

I am writing these for a two-columned document. I have quite long equations, and it has been a headache to split them so that they look nice and at the same time fit the column width.

Code: Select all

\documentclass{article}
\usepackage{mdwmath}
\usepackage{mdwtab}
\usepackage{array}
\usepackage{subfig}
\captionsetup{belowskip=0pt,aboveskip=0pt}
\usepackage{bm}
\usepackage{nccmath}
\begin{document}
\begin{fleqn}[0pt]
\begin{equation} \label{eq:11}
\begin{split}
A + B + C + A + B + C + \\ A + B + C + A + B + C + A + B + C + A + B  \\+ C + A + B + C + A + B + C + A + B + C + A + B +  C + A + \\ B + C + A + B + C + A + B + C + A + B + C + 
\end{split}   
\end{equation}
\end{fleqn}
\end{document}

But whatever i do, it still looks ugly, and for some reason equations appear to be right aligned (I want nice looking left aligned equations for only these long equations, the rest of the paper is okay). I have done everything I could.

Thanks for your help

The split environment is for multi-line equations with alignment. Similar to the align environment, equations are aligned at the & symbols. If there's no such alignment symbol, they will be right aligned. Alignment of such split columns is: first column right aligned, second column left aligned. So, the quickest fix would be to start each line with a &.

Or use another environment, such as multline, or flalign.

That's really helpful. I was very close. I tried several configurations of & but not the one you suggested. Thank you!
