You can get a Mangold Nemeth teaching system through Exceptional Teaching
Aides, but typically I just teach the symbols as they are introduced in
the General Education Math Curriculum. Initially I previewed them with the
student before they appeared in the textbook. Now that my braille student
is older when sometimes new symbols are introduced she figures them out
through class discussion and the transcriber notes. If there are symbols
that she doesn't understand or are tricky we discuss them during our
resource time at the end of the day so she fully understands how to read
them and how and when to write them before she has to do homework.

What are teachers using to teach students the Nemeth code in public
schools? Is there a series for math like Patterns is for Literary?

the Nemeth rules are finicky about how that double minus may be written
and how then it should be written in Braille.
Look carefully at the font of the second minus sign. Is it in any way
superscripted? More and more frequently negative numbers are showing up
with that minus sign being in superscript. In that case, the negative
sign needs to be supered. So, in Braille, the expression would be:
7-~-"1
with the tilde representing the superscript mark and the quote
representing the baseline marker necessary to indicate that the
superscript applied only to the minus sign.

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
