letter sign

x-coordinate of M = 9/2

Do you braille it as you would if it were "M =" and omit the letter sign

;x-coordinate of ,m .k 9/2 or

as you would if it were "x-coordinate of M" =

;x-coordinate of ;,m .k 9/2

x-coordinate of M = 9/2
should be transcribed as follows:

[simbraille];x-coord9ate ( ,m .k #9_/2[/simbraille]

Because the M is next to the sign of comparison, it should not have a letter indicator. See §55.a in the Nemeth Codebook.

Nemeth: (no UEB)

Question - if you had:

1. Subtract ab from both sides.  Would you  have ab with a letter indicator in front of the a?
2. How can you isolate w?  Would the w have a letter sign or no?
3.  You can rewrite the right side as two terms, c = x−a−ab−a,.... etc.  Is there a letter sign in front of the c or no?

I know this is probably a basic question but I just want solid clarification on it.  I think I find an answer but then I'm not sure.  Thank you!

Consider the equation  m−n = 4p.  Do not use letter indicator on the m because it is attached to -n and it's next to the equal sign, correct?  🙂   thanks again.

Thank you for checking in 🙂

If you're transcribing in Nemeth Code (with EBAE), no UEB:

1. "Subtract ab from both sides."  An English Letter Indicator should precede the short-form letter combination ab
2. "How can you isolate w?" An English Letter Indicator should precede the single letter w (and a punctuation indicator should precede the question mark that follows this variable).
3.  "You can rewrite the right side as two terms, c = x−a−ab−a,…. etc."  An English Letter Indicator should not precede the c because it is immediately followed by a symbol of comparison.
4. "Consider the equation  m−n = 4p" An English Letter Indicator should not precede the m because it is part of the unspaced mathematical expression m−n

Sections 25 and 26 of the Nemeth Code are super relevant to your questions. They can be a little "wordy," but they cover some important Nemeth/EBAE overlap.

Again, thank you for checking in. And thank you for your questions.

Awesome - I think I only forgot the punctuation mark before the period - so I was close!  Thank you again!

I have the yellow "An Introduction to Braille Mathematics" and it's wording can be a bit confusing.

Nemeth Code for Mathematics & Science Notation, 1972 Revision.

Is this the manual you are referring too?  I probably need to print it as I prefer searching and making notes in actual print form - not e-form.

The book whose sections I referenced is the Nemeth Code itself, also known as “the green book.” More information about it (and other code books & resources) is here (that is a link) and on BANA’s website.

Nicely done! –Kyle

Thanks -  I did order that book last week - I thought I had it but it may have been at the school I last worked at!  Thank you!  You are very helpful!  🙂
