[Blindmath] Subscript and superscript notation and mathml

[John Gardner]

Karen, the answer is "it depends". But it is largely accurate to say that sub and superscripts need to be in some standard math notation and not just shown in sub or superscript position in Word, HTML, etc. MathML is good, but LaTeX is often readable too - where one would read x^3 for x cubed for example. 

Math is still a moving target. And the target is really moving slowly. But still it is possible for authors to write math nowadays so it is both mainstream and accessible. This was not true a decade ago.

Subject: [Blindmath] Subscript and superscript notation and mathml

Hi -
I have been under the impression that subscript and superscript math and science notation (ie, exponents) had to be in MathML to be accessible. Is that true? I understand that if the number with the exponent is in an equation, it should be in MathML, but if there is just a number with an exponent, does it have to be in MathML for a screen reader to read it accurately?
Thank you for your advice.
Best,
Karen
