equationElementElementElement functions can be customized with set and show rules.
set and show rules.A mathematical equation.
Can be displayed inline with text or as a separate block. An equation becomes block-level through the presence of at least one space after the opening dollar sign and one space before the closing dollar sign.
Example
#set text(font: "New Computer Modern")
Let $a$, $b$, and $c$ be the side
lengths of right-angled triangle.
Then, we know that:
$ a^2 + b^2 = c^2 $
Prove by induction:
$ sum_(k=1)^n k = (n(n+1)) / 2 $
By default, block-level equations will not break across pages. This can be
changed through show math.equation: set block(breakable: true).
Syntax
This function also has dedicated syntax: Write mathematical markup within dollar signs to create an equation. Starting and ending the equation with at least one space lifts it into a separate block that is centered horizontally. For more details about math syntax, see the main math page.
ParameterParameterParameters are input values for functions. Specify them in parentheses after the function name.

Default value: false
numbering
How to number block-level equations.
Show example
#set math.equation(numbering: "(1)")
We define:
$ phi.alt := (1 + sqrt(5)) / 2 $ <ratio>
With @ratio, we get:
$ F_n = floor(1 / sqrt(5) phi.alt^n) $
Default value: none

set rule, changing the default value used thereafter.The alignment of the equation numbering.
By default, the alignment is end + horizon. For the horizontal
component, you can use right, left, or start and end
of the text direction; for the vertical component, you can use
top, horizon, or bottom.
Show example
#set math.equation(numbering: "(1)", number-align: bottom)
We can calculate:
$ E &= sqrt(m_0^2 + p^2) \
&approx 125 "GeV" $
Default value: end + horizon
supplement
A supplement for the equation.
For references to equations, this is added before the referenced number.
If a function is specified, it is passed the referenced equation and should return content.
Show example
#set math.equation(numbering: "(1)", supplement: [Eq.])
We define:
$ phi.alt := (1 + sqrt(5)) / 2 $ <ratio>
With @ratio, we get:
$ F_n = floor(1 / sqrt(5) phi.alt^n) $
Default value: auto
bodyRequiredRequiredRequired parameters must be specified when calling the function.PositionalPositionalPositional parameters can be set by specifying them in order, omitting the parameter name.
