Template:Eqn

Usage
Used to add new rows of aligned math text.

  needs to be called first.

You can add a new general row in the following manner:

The different possible variables that can be used are:
 * 1) n - Right at the very far left (when needed), to be used for numbering, i.e. for labels.
 * 2) ll - Furthest left column (used only when needed).
 * 3) l - General left column.
 * 4) o - Operator, defaults to $=$
 * 5) r - General right column.
 * 6) rr - Furthest  right column (used only when needed).
 * 7) c - Comment
 * 8) cc</tt> - Extra comment (used only when needed).

Math delimiters (i.e.  $ ... $ </tt>, or  \( ... \) </tt> etc.) must be used only on the c</tt> and cc</tt> lines.

Once the full equation is completed,  </tt> must be called.

Warning
Do not put two closing curly brackets together, e.g.  }} </tt> because the interpreter thinks this marks the end of the template and it breaks the syntax.

Put a space between them:  } } </tt>

Also beware: $|$ can not be included anywhere in $\LaTeX$ used to define equations using this template. Your best bet is either to use  $\mid$ </tt> or define any constructs using this character in a \newcommand</tt> command.

Other constructs may also misbehave. Please beware.

Example
gives:

 * align="right" | \(\displaystyle \)
 * align="center" | \(\)
 * align="left"  | \(\displaystyle \)
 * align="left"  | \(\)
