[blindkid] [Bulk] subtracting in Nemeth braille

[Brandy W]

Hi, When I do subtraction on the Braille Writer I don't use extra signs. One 
doesn't need to cross it out. If need be she could just put a 4 sign over 
it. Once I was profeciant we moved on to the abacus. Much faster and makes 
more since. Hope this helps. Bran
