Have you come across the math problems where the carryover number is in the sub-total line? I am attaching a copy for your review. Will you provide us with information as to how you would braille this. (We have discussed this and have two possible solutions.) Please advise as soon as possible.
I believe you are asking how to braille the illustration of the "New Groups Below" method that's shown on the print page you attached.
There is not a specific Nemeth rule for this situation. I would suggest using the "carried number indicator" (explained in Nemeth Code §178.d) much as you would for the "New Groups Above" method. Attached is an image of the braille I might use.
You should include a transcriber's note explaining that "the numbers printed on the separation line are brailled between the separation line and the carried number indicator". edited by kdejute on 9/5/2015
