The pair of templates {{EquationRef}} and {{EquationNote}} is used for labeling equations in text.

For example, {{#if: |{{#if:||}}

:{{EquationRef|Eq. 1}} <math>x^2+x+1=0</math>
{{#if: |{{{2}}}|Eq. 1}} $x^{2} + x + 1 = 0$ |*:{{EquationRef|Eq. 1}} <math>x^2+x+1=0</math>

{{#if: |{{{2}}}|Eq. 1}} $x^{2} + x + 1 = 0$ }}{{#if: |
}}{{#if: |
}}{{#if: |
}}{{#if: |
}}

Here, the identifier "Eq. 1" is a label which can be later referred to with a call to {{EquationNote}}. That is, {{EquationNote|Eq. 1}} produces a link {{#if:|{{{2}}}|Eq. 1}} to this equation.

Similarly, {{#if: |{{#if:||}}

:{{EquationRef|2|Eq. 2:}} <math>x^2-2x+1=0</math>
{{#if: Eq. 2:|Eq. 2:|2}} $x^{2} - 2 x + 1 = 0$ |*:{{EquationRef|2|Eq. 2:}} <math>x^2-2x+1=0</math>

{{#if: Eq. 2:|Eq. 2:|2}} $x^{2} - 2 x + 1 = 0$ }}{{#if: |
}}{{#if: |
}}{{#if: |
}}{{#if: |
}}

which can be referred to by {{EquationNote|2}} or even {{EquationNote|2|Equation 2}} (i.e., {{#if:Equation 2|Equation 2|2}}).

This template can be used together with {{NumBlk}} to produce nicely formatted numbered equations. For instance:

{{NumBlk|::|<math>x^2+x+1=0</math>|{{EquationRef|3}}}}

x^{2} + x + 1 = 0

{{#if:|

|}}

{{#if:|{{#if: |{{{2}}}|3}}|{{safesubst:#if:1|{{#if: |{{{2}}}|3}}}}}}

which may then be referred to by {{EquationNote|3}} or even {{EquationNote|3|Eq. 3}} (i.e., {{#if:Eq. 3|Eq. 3|3}}).

{{NumBlk|::|<math>x^2+x+1=0</math>|{{EquationRef|4|Eq.4}}}}

x^{2} + x + 1 = 0

{{#if:|

|}}

{{#if:|{{#if: Eq. 4|Eq. 4|4}}|{{safesubst:#if:1|{{#if: Eq. 4|Eq. 4|4}}}}}}

which may be referred to by {{EquationNote|4}} (i.e., {{#if:|{{{2}}}|4}}).

{{NumBlk|::|<math>x^2+x+1=0</math>|{{EquationRef|Eq.5}}}}

x^{2} + x + 1 = 0

{{#if:|

|}}

{{#if:|{{#if: |{{{2}}}|Eq. 5}}|{{safesubst:#if:1|{{#if: |{{{2}}}|Eq. 5}}}}}}

which may be referred to by {{EquationNote|Eq. 5}} (i.e., {{#if:|{{{2}}}|Eq. 5}}).

The common shorthand (#) can be written using {{EqNote}}, e.g. {{EqNote|5}} gives ({{#if:|{{{2}}}|5}})
