Dear sir, When I convert the mathml content for squareroot of (3+2+4)+5 what I get as braille format is >3}+2+4 +5 But this corresponds to sqrt of(3)+2+4 +5 and it's not the corresponding conversion for squareroot of (3+2+4)+5 I think this ca be done by modifying msqrt msqrt ^>,^} line in nemth.sem file. But i don't know how to do it. Can you please help me to fix it? Thanks! -- Chathuri Gunawardhana Undergraduate at University of Moratuwa Sri Lanka
