[BlindMath] Long Math Problems

[Susan Jolly]

Hi Nicholas,

You've already gotten some good suggestions so I''ll just focus on the 
problem with underscripts and overscripts or what Nemeth calls modifiers 
that are common in statistics. These expressions are unavoidably verbose in 
Nemeth or other linear system,  If I've counted right  the sum from n equals 
zero to 10 is already sixteen characters in Nemeth and thirteen in LaTeX 
before you even get to the expression for what is being summed.

I suggest representing modified symbols with a shorthand defined on a 
separate line. For example you could use the small letter ess followed by a 
digit to identify a particular sum and then a dot 5 separator which is only 
three braille cells.

HTH, Susan J
