Here are my thoughts on the symbol :=
Because the symbol has been defined to mean "is defined as equal to" it is one sign so should not be broken up.
If the expression fit on one line, there would be no space before the colon. A punctuation indicator would precede it. So it will be a 4-cell symbol, with a space following the equals sign. (456, 25, 46, 13, space)
This expression does not fit on one line. Our division rules say to divided before a comparison sign on the baseline of writing. I feel that the first runover line can begin with the punctuation indicator. This is an unusual formation so you should identify the symbol in a transcriber's note. Something like this: "The symbol ___ means "is defined as equal to". It is printed as a colon immediately followed by an equals sign."
I see no discrepancy in the division sites you have chosen. I am tempted, however, to make an exception to "displayed" format here and start the expression in cell 1, after a blank line. This will allow you to keep the "C" portions together on one line. This is breaking a format rule, but there are times when it benefits the reader to do so.
I think you need to insert a space after the word "Gain" as I believe it is a function name.
See the attached brf file for my suggested transcription of this long expression.
I invite anyone to chime in if my solution is problematic.

Hi Connie.
Yes, I have seen this symbol before and have wondered how to handle it. It will take me some time to go through my notes. I'll get back to you soon.

Hmm. This is really a Braille Formats question. Can you repost it there? It would be helpful if you attach a pdf scan of the table in question.

Hi Cheri. Can you determine the meaning of the asterisk? This may affect how it is transcribed. If you can post a snippet of the surrounding text for some context, I can offer some advice.
Lindy
I have further comments.
We have no rules or guidelines regarding comments to only one line of a spatially-arranged problem. I like your idea of placing the uncontracted comment to the right of the labeled line as long as the comment is short enough to fit on that line, as it does here.
"x = 1" is not part of the spatial arrangement. It should be transcribed after the blank line following the spatial portion and its comment should be placed on the following line as you do for other linear portions.
See the attached brf file.

Hi Shellee.
Sorry for the delayed response. Happy New Year!
Yes, Nemeth continues to be in effect through a braille page turn.
In the sample you sent, the opening Nemeth Code indicator should be placed at the beginning of line 25 in order to be on the same line as the math to which it applies (embedded format).

Hmm, interesting solution. I think that sentence in the lesson book needs to be rewritten. "regardless of its meaning" is referring to whether it means feet, or minutes of arc, or a derivation of a similar item such as A and A'. The statement should read "regardless of its *mathematical meaning".
The new Nemeth punctuation list include the UEB single quotation marks. The opening (left) single quotation mark is (6, 236) as it always has been. The closing (right) single quotation mark is (6, 356). In your example, if you are certain these are punctuation marks, you should use those symbols.

Hi Tonya.
Nemeth format rules require that the abbreviation "Fig." and "P10.22" stay together on the same line, even in UEB context. However, because "and" is a connecting word which is not itself part of the abbreviation, the line can wrap either before or after the word.

Keying is usually the last option to consider because it requires a lot of back-and-forth reading. I would not recommend keying here.
I believe the arrows are simply pointing to the row—they are not mathematical signs of comparison. So yes, this will fit as long as you begin in cell 1. Even though this is displayed material, by starting in cell 1 you will not need to rearrange the matrix. This is the preferred method.
In order to maintain the alignment of the math portion, comments are transcribed to the right of the labeled line. Explain what the print copy looks like in a transcriber’s note. Something like “Row operations (printed in blue) appear to the left of each labeled row. An arrow points from the label to the row. In braille, the row operations are transcribed to the right of each labeled row and the pointing arrow is omitted.”
Regarding the vertical dotted lines, the BANA Nemeth committee has decided to use the Nemeth vertical bar (preceded and followed by a space) to represent the vertical line in an augmented matrix. This will be explained in the not-yet-available new edition of the Nemeth code book, but there is no reason you cannot use it now as long as you identify it with a transcriber’s note.
I have attached my transcription of this problem. Please check for errors if you are going to be copying it.

1. This transcription clearly shows the extent of the enlarged parentheses. (Note there is an error on line 4-dots 56 should be only dot 6.)
2. The enlarged parentheses are disrupted in this transcription. I think it conveys wrong information.
3. This is also an acceptable transcription.
I vote for transcription #1.
Lindy
Oh, yes, of course -- the alternate form! I suppose to be entirely accurate you should capitalize the letter, but since you are inventing the symbol I think it is okay to keep it to a 3-cell symbol. Your choice.
I think I answered my own question. It seems that the underlining shows what syllable is blended with the next or previous word. In braille, we show this by using quotation marks, so the underlining is unnecessary. Do I understand this correctly?

Hi Aquinas
As you know, there is no braille symbol assigned to an inverted capitalised Greek omega ℧, so you will need to create one and list it as a special symbol.
My first inclination is to create a symbol that hints at the meaning. I looked up Navier-Stokes equation on Wikipedia in order to get an idea what this symbol means, but only an upright Omega is used there. I looked up dimensionless velocity as well, with no luck. I asked a physicist. He's never seen this before.
You are free to create any symbol as long as it doesn't have another meaning in Nemeth. (Searched Appendix B of the Nemeth Code to be sure the new symbol is not listed there.) Since an upright Omega is (46, 6, 2456), it makes sense to me to make the upside-down version be (46, 4, 2456). By using the same base "2456" for omega, it will be easier for the reader to recognize within the formulae.
Let me know if this works for you.
