Reply To: Displayed material
Susan,
Kudos to you for spending quality time with the Guidance for Nemeth in UEB.
First, if displayed mathematical material and its opening and terminating indicators will all fit on one line together, it is suggested that this be done.
Second, if displayed mathematical material takes up more than one line, then the opening Nemeth Code indicator could legitimately be placed at the end of the text that precedes the displayed material or in the first cells of the line on which the displayed material begins.
The examples you reference illustrate these two options. On page 4 of the Guidance, the opening Nemeth Code indicator is placed at the end of the text that precedes the displayed material and so does not mess with the alignment of the linked material that follows.
On page 6 of the Guidance, the opening Nemeth Code indicator is on a line with the beginning of the displayed material. It does not muddy the alignment of the displayed material or affect its line breaks. If the opening Nemeth Code indicator in this example had been placed at the end of the preceding text, it would have forced another line, because it would not fit on the braille line with the end of the text that precedes the displayed material.
Last but not least, if displayed mathematical material takes up more than one line, then the Nemeth Code terminator could legitimately be placed on the same line as the end of the displayed material (if that material is NOT spatial) or on a line by itself. Most of the time, the terminator will fit and should be placed on the same line as the end of the displayed material.
So, when deciding where to place Nemeth Code indicators when nonspatial displayed material takes up more than one line, consider 1) alignment of the displayed material, 2) line breaks of the displayed material, and 3) line breaks of the preceding text.
