Because the number lines in your book show two arrows, the standard instructions given in section 6.5.1 of Guidelines and Standards for Tactile Graphics are not going to work here. I am going to run this by others on the Nemeth committee to come up with some ideas for you. Thank you for the challenging question!

Following the rules of the Nemeth Code, here is how to transcribe 7.EE.A.2 and MP.2 in an EBAE transcription. The multipurpose indicator (dot 5) comes into play.
7.EE.A.2
#7.",E,E.",A".2
MP.2
,M,P".2
When transcribing in "EBAE and Nemeth" there is no switching between codes -- the entire transcription follows Nemeth Code rules, even for numbers and letters within the document that are not mathematical constructs. 7.EE.A.2 and MP.2 will need to follow the rules of the Nemeth Code in an EBAE transcription. I will post the simbraille for these two soon -- I need to run this by the committee. Thank you for your question.
Thanks for the information and pathway to finding the Nemeth interpreter in Braille2000. It seems to be very basic, not showing levels like it used to do in version 1.
Hi Shelley. What your attached image shows is not a system of equations, as far as I can tell. The text which precedes these four equations says "Each equation represents one of the hanger diagrams." I'm not familiar with hanger diagrams, but it seems from the text that these are four separate equations. 2y = x is a simplification of the other three equations in your example,
If the student is asked to express one variable in terms of another, that would be solving a system of equations. For example, that second equation "2y = x" is expressing x in terms of y. That might be a solution to a system. But in this case, it is just simplifying the terms of each of the other three equations.
If there is a mathematician reading this, please correct me if I am misinterpreting this topic. Maybe you can explain it better? Is "system of equations" an outmoded term?
Thank you.

Hi Susan. Thank you for your question. Actually, the DXB translation is correct. The "ow" symbol is the contracted form of the comma which is used to represent the comma and the space in the subscript position. Nemeth Code, Section 78, is where you will find the rule.

Beth, you really have me thinking on this one! I "asked my expert" chemist about the significance of the print layout and her answers are copied below, in italics. If I am understanding her correctly, it seems to me that the arrangement of the diagrams is significant, which, to me, points to a good reason to use tactile graphics. By reproducing the drawings, you will not need to try to interpret what they mean. The possibility of giving the wrong interpretation is too risky.
FIRST EXAMPLE (sp and 2p and x's) (I asked "Is there a reason the 2p diagram is raised higher than the sp diagram?") ANSWER: It is important to note that the 2p diagram is raised to indicate that it is a little higher in energy than the sp diagram. The x's may be indicating that there will be other electrons from another atom bonding to that carbon atom that has sp hybridization. That would be my guess based on the little bit of wording that was copied over.
SECOND EXAMPLE (the more complex display) (I asked " Is there significance to the vertical alignment of the energy arrows? That is, are the six configurations related to one another and is that why the text has aligned them in this manner?" ANSWER: The alignment is intentional because the orbitals at the top of the image are highest in energy and the ones at the bottom are lowest in energy. It is also important to keep the ones that have two lines with electron arrows the same because those denote two orbitals that are at the same energy level.
I hope this helps.

Hi Julie. I honestly do not know if Larry's Speakeasy is available in braille.
Can anyone answer Julie's question?
Lindy
Beth, I am not familiar with this notation. I'll get back to you after conferring with some chemists.

FYI, I have corrected my original post. I thank Kyle DeJute for her knowledge of UEB-Technical.
The reason a grade 1 indicator is NOT needed for ::/128 is because when we get to the slash, it becomes impossible that the preceding cell of dots 25 could represent any contraction, and once that is established, it then becomes impossible that the first cell of dots 25 could be any contraction [because both the "con" and the "cc" contractions must be followed "by a letter, a contraction, a modified letter or a ligatured letter"].
Please address further questions about computer language to the UEB Technical forum.Thank you.LindyHi Carmen. The Nemeth Code does not address computer notation. In a UEB transcription, if the print is "computer notation" as defined in Section 17.1 of the UEB Guidelines for Technical Material, then follow the directions in that section (Section 17, Computer Notation), even in a Nemeth/UEB transcription.
Your example would be transcribed like this:
33_/#ABHYou might like to read the post from December 20-23, 2019, titled "computer notation" in the Unified English Braille Technical section of this Ask An Expert forum.

Hi. Thank you for asking these important questions.
Regarding question 29, yes, a space must precede the open parenthesis. The 2007 update to Section 119.a of the Nemeth Code says this: "A space must be left after an unmodified function name or its abbreviation. If the function name or its abbreviation carries a superscript, subscript, modifier, or other braille indicator, the space must follow the superscript, subscript, termination of modifier, or other braille indicator."
Regarding questions 30 and 41, 3:4:5 is a ratio. It means that the side lengths are in the ratio of 3:4:5.

Hi. Yes, you are right, this matrix equation will not fit on a braille page without having to divide it. The first priority is to divide before the equals sign, as you have done.
I have attached a brf example for you which includes the following corrections:
- Starting the displayed matrix in cell 7 (it is displayed to 1-5 text--NC Sec.191.b.iv);
- Aligning "a" with "3" in the first matrix (items in the same column must begin in the same cell in a matrix) (NC Sec.183.a);
- Deleting the space before the plus symbol (operation symbols are generally unspaced--NC Sec.138.b);
- Deleting the second equals symbol (the equals symbol is transcribed on the top line of the arrangement, just as you have done with the plus symbol)(NC Sec.183.a).
Since some of the answer choices contain decimals, I would not terminate Nemeth Code until after subitem K. is completed unless, of course, Nemeth Code continues with item 27.
Hope this helps!
Lindy
