[Blindmath] Subscript and superscript notation and mathml

[Star Gazer]

				John, 
I have often thought this, that until recently it wasn't possible for
authors to write math so that it was both mainstream and accessable. Can you
explain why exactly? I'm mostly looking for words to use to explain it to
others.

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.

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
