[Blindmath] Subscript and superscript notation and mathml

[Karen Sorensen]

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
