A closing fraction indicator in Nemeth is the same as a number sign.

• A. False
• B. True
• C. Not defined
• D. Irrelevant

Answer: (B)

In Nemeth Braille, some indicators share the same Braille pattern to keep the system compact. The symbol used to start a number, the number sign, is also the marker used when signaling the end of a fraction—the closing fraction indicator. The meaning you read depends on where it appears and what comes before or after it in the math expression. Because of this contextual usage, the closing fraction indicator is the same symbol as the number sign. So the statement is true: they are the same indicator used in different roles depending on context.
