Hi. Rule XI states that the cancellation indicators must be used to show the extent of a mathematical expression which has been cancelled in ink print. And says a spatial arrangement must be used when cancellation is represented in braille. This is the equation:
____ = 4,000 - 4,000 + 500 + 2 - 2 (in ink print the 2's are cancelled out)
Since this is not spatial how do I represent this.
Thank you,
Sue

Hi Sue. It would help me if you could send me a pdf copy of the print, but here is my answer based on what you have said in your note. The line on which this equation falls should be preceded and followed by a blank line. I am wondering if it isn't only the 2s that are cancelled -- it is more likely that the +2 and the -2 are cancelled -- look closely at the print to determine what needs to be brailled between the cancellation indicators.
