# Template:Equation/doc

This is a documentation subpage for Template:EquationIt contains usage information, categories and other content that is not part of the original template page. |

This template, whose format is

{{Equation|formula|number (optional)|alignment (left by default)}}

allows equations to be offset from the main text, numbered, and anchored for later referencing using the template {{Eqnref|x}} (see final note), where x is the number of the equation. The equation is offset 10px from the text above and below. For example,

- {{Equation|<math> x^2 + y^2 = z^2 </math>|1}}

results in:

(1)

The number is optional and can be omitted as in

- {{Equation|<math> x^2 + y^2 = z^2 </math>}}

which gives:

The third variable acts to align the equation to the left, center, or right (this last alignment is not recommended, but is available) and with an indentation of 5% of the width of the page. For example:

- {{Equation|<math> x^2 + y^2 = z^2 </math>|2|left}}

results in:

(2)

and

- {{Equation|<math> x^2 + y^2 = z^2 </math>|3=right}}

results in:

**Note:** The equations are anchored by number for use with Template:Eqnref

- {{Eqnref|1}} {{Eqnref|2}}

results in:

- ( ) ( )

Clicking on (

) or ( ) jumps to the correspondingly numbered equation.
