LaTeX (or an AMS variant thereof) has \vmatrix. Isn't this unambiguously a determinant? \abs{} and \card{} seem to be needed in any case. Thanks, Murray -----Original Message----- From: David W. Farmer <farmer@aimath.org> Sent: Wednesday, December 7, 2022 10:01 AM To: www-math@w3.org Subject: [EXTERNAL] Re: MathML Core authoring tools? It is a good idea to have a LaTeX file that tests MathML core. It will also serve as a quick way for people to see how to author various constructions. Are there ideas for how the LaTeX source will be aware that |A| means absolute value (or whichever of the many other things it might mean)? I think it is reasonable to have several macros \abs{A} \det{A} \card{A} all of which render as |A| . But where is the information which provides the intent?
