equationElementElement functions can be customized with set and show rules.
Element functions can be customized with
set and show rules.A mathematical equation.
Can be displayed inline with text or as a separate block.
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 $
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.
ParametersParameters are the inputs to a function. They are specified in parentheses after the function name.

Default: false
numbering
How to number block-level equations.
Default: none
View 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) $
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.
Default: auto
View 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) $
body
The contents of the equation.
