The pair of templates <nowiki>{{tl|EquationRef}}</nowiki> and <nowiki>{{tl|EquationNote}}</nowiki> is used for labeling equations in text.

For example, 

* <code><nowiki>:{{EquationRef|Eq. 1}} <math>x^2+x+1=0</math></nowiki></code>

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

Here, the identifier "'''Eq. 1'''" is a label which can be later referred to with a call to <nowiki>{{tl|EquationNote}}</nowiki>. That is, <nowiki>{{tlb|EquationNote|Eq. 1}}</nowiki> produces a link <nowiki>{{EquationNote|Eq. 1}}</nowiki> to this equation.

Similarly, 

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

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

which can be referred to by <nowiki>{{tlb|EquationNote|2}}</nowiki> or even <nowiki>{{tlb|EquationNote|2|Equation 2}}</nowiki> (i.e., {{EquationNote|2|Equation 2}}).

This template can be used together with <nowiki>{{tl|NumBlk}}</nowiki> to produce nicely formatted numbered equations.  For instance:

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

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

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

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

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

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

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

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

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

The common shorthand '''(#)''' can be written using {{template|EqNote}}, e.g. {{tlb|EqNote|5}} gives {{EqNote|5}}
