Reply To: Multiple equations on a line, revisited
I consider this kind of thing to be an author's comment to the equation, in which case I usually place it following on the same line in braille with any runovers in the established runover position. I don't believe there is a rule specifically addressing this situation. If there could be confusion about the "meaning' of this additional material, and it is not differentiated in print with a comma or other punctuation, I have, on occasion, placed a note on the TN page stating that comments to equations or procedures are enclosed in brackets (or whatever) and follow on the same braille line.
