Hi Katie,
The person who indicated that you use only one subtraction symbol mustn't have
realized that doing that would change the nature of the question.
Mathetmatically speaking,
7 - -1 = ?
is the same as
7 + 1 = ?
You cannot "drop" one of the subtraction symbols, because it would change the
nature of the question. Instead, you would probably be best to Braille it as
7 - (-1) = ?
... keeping both negative signs but putting the negative one in brackets.
This is coming from someone who used Nemeth throughout high school and
first-year university courses, but who has no official 'transcribers' training
or anything of the sort. I do know, however, that you can't just "drop" a
negative sign in the Braille and retain the same meaning!
Take care,
Anthony
