{{#invoke:Math templates|subst|math|arg1|arg2|...}}
Prints math
inside math tags, with the arguments substituted in. Use ${n}
to invoke substitution of parameter n
, drawn from the arguments to #invoke
.
For instance,
{{#invoke:Math templates|subst|${2} + ${3} = ${4}|a|b|c}}
expands to
<math>a + b = c</math>
display
is special: it becomes the same-named attribute of the math tags.
