Math & Science ⇒ New Command or Environment for split Equations

[thorpn]

I like having shortcuts for the commands I use the most when taking notes, I already have a command for \begin{\equation} and \end{\equation}. However I find that I often have to use the \split command to make the math understandable and so I need a shortcut for this, however as split requires the equation environment I have to use two shortcuts can it be done in one command? Something like:

Code: Select all

\newcommand{\bes}{\begin{equation}\begin{split}}

P.S.: No minimum working example included since I figure one won't be needed!

You could define an environment for both, such as

Code: Select all

\usepackage{environ}
\NewEnviron{es}{%
  \begin{equation}\begin{split}
    \BODY
  \end{split}\end{equation}
}

Thx Stefan, almost there I think. When I use the \begin{} command for the environment directly it works fine, however i want to use shortcuts so I have done this:

Code: Select all

%Laver et environment til equation split (der er 2 kommandoer så lidt kompliceret..)
\NewEnviron{split.enviro}{%
\begin{equation}\begin{split}
  \BODY
\end{split}\end{equation}
}

%Begin equation split: Begin equation split = bes
\newcommand{\bes}{\begin{split.enviro}}
\newcommand{\ees}{\end{split.enviro}}

But when i instead of \begin{} use \bes it fails, it looks like it doesn't find the end of the environment (I do end the area with the \ees command)


Thx
