In line with [[recommended Latex practice -> http://www.tug.org/pracjourn/2006-4/madsen/]], the recipe wraps the equations in the ''align'' environment, rather than using ''eqnarray''.

24 October 2008 at 10:01 AM by John Rankin - explain subequation numbering
Changed line 32 from:
As of Wikipublisher version 2.2.7, the markup lets authors define a subequation set. Note that in the web page view, numbering restarts at 1:
to:
As of Wikipublisher version 2.2.7, the markup lets authors define a subequation set. Note that in the web page view, it continues the numbering where the previous equation left off. However, if an author adds a new numbered equation above this one, the image numbering does not change, as the image is generated once and stored.
23 October 2008 at 08:36 PM by John Rankin - add subequations reference example
Changed line 34 from:
{$# f = g $}
to:
{$subbie, f = g $}
Added lines 37-38:

References to aligned subequations are supported and it correctly counts the preceding aligned equation numbers: Eq(subbie) shows this.

Changed lines 1-2 from:
The [[LatexEquations |Latex Equations]] page illustrates inline mathematics and simple equations. This page illustrates how to group and align several equations. It uses the existiing [={$ ... $}=] equation markup.

{$# f = g $}
{$ f' = g' $}

Changed line 3 from:
{*This page broke under `PmWiki 2.2.0 beta 65 -- now fixed.*} In 2.2, the rule for evaluating character entities moved nearer the start of the evaluation sequence. This caused equation markup to evaluate before equation array markup, instead of after, so the arrays were interpreted as individual equations.

to:

The simplest unnumbered form just aligns to the relation symbol:

{$* (a + b)^3 = (a + b) (a + b)^2 $}
{$ = (a + b) (a^2 + 2ab + b^2) $}
{$ = a^3 + 3a^2b + 3ab^2 + b^3 $}

Added lines 1-24:
The [[LatexEquations |Latex Equations]] page illustrates inline mathematics and simple equations. This page illustrates how to group and align several equations.

Here is a group of aligned equations, with numbering (automatically set flush right):

{$ 1+1 = 2 $}
{$ 4 = 2 \cdot 2 \nonumber $}
{$ a + b \le c $}
{$ d + e > f $}
{$ \sin x = x -\frac{x^{3}}{3!} + \frac{x^{5}}{5!} - \frac{x^{7}}{7!} +{} \nonumber $}
{$ {}+ \frac{x^{9}}{9!} - {}\cdots $}

Here is an unnumbered group of aligned equations (automatically centred):

{$* x^2 + y^2 = 1 $}
{$ x = \sqrt{1-y^2} $}

Here is an unnumbered group of aligned equations, with 2 alignment positions, plus an intermediate line of text:

{$* x &= y && \text{by hypothesis} $}
{$ x' &= y' && \text{by extension} $}
{$\intertext{And finally:} $}
{$ x + x' &= y + y' && \text{by Axiom 1} $}

In line with good Latex practice, the recipe wraps the equations in the ''align'' environment, rather than using ''eqnarray''.
