Summary:
To get VoiceOver to read a minus sign as "minus", the unicode minus sign (U+2212) must be used. If VoiceOver is set to 6-dot braille on iOS or Mac or 8-dot braille Mac, the minus sign is sent to refreshable braille displays as "*b" (star b).

Steps to Reproduce:
1a.) Set a label (or accessibility label) to an mathematical expression with a minus sign.
*OR*
1b.) Type a mathematical expression with a minus sign into a text field.
2.) Have VoiceOver read the expression allowed, to make sure an actual minus sign was used.
3.) Read the expression on a refreshable braille display.

Expected Results:
The minus sign should display on the refreshable braille display the same as a hyphen-minus. This would make sense, as VoiceOver displays the multiplication cross (U+00D7) as a star and the division sign (U+00F7) as a slash on a refreshable braille display.

Actual Results:
The minus sign displays as "*b" (star b) on refreshable braille displays.

Regression:
This affects both OS X and iOS.
