\triangle in LaTeX vs. $triangle.t$ in Typst

[hpcfzl]

I believe Typst decides math.class for every operator, and triangle.stroked.t appears to be "binary" by default.

Follow this other solution to alter math.class of a symbol:

Forcing unary minus in math

try math.class: $ "if" class("unary", -) x $ maybe #let umin = math.class("unary", $-$) $ "if" umin x $ perhaps even #show sym.minus: math.class.with("unary") $ "if" -x $

So, for example:

#set text(font: "New Computer Modern")
#show math.equation: set text(font: "New Computer Modern Math")

#show sym.triangle: math.class.with("unary")

Let $A triangle B$.
