In Excel spreadsheets the formulae are all together, so not spaced. Should we space the formulae as the Nemeth rules state or should we disregard and run everything together? Our concern is that if the book is teaching the student how to enter in formulae we would want to keep it all together, but we don’t want to break Nemeth Code rules. I will include a copy of the print page in question. Notice column K row 7 at the bottom left of the page has numbers with commas. There are also equals signs, etc.
Sorry for the delay. We feel that Nemeth symbols should be used, and that the spacing should follow print. I can see how there are times the transcription will be ambiguous. Those cases may benefit from a transcriber's note explaining. Are you disregarding the capitals? If so, the commas will be unlikely to be misread.
Please send examples of formulae that you find to be difficult. It would be interesting to see how they look in braille.
