Usage notes[edit]

  • Often in typography (and always in computer programming), the hyphen (-) is used instead of the minus sign (−); in many fonts, the symbols are barely distinguishable or not at all (although the difference is clear in Times Roman). Careful typographers use the minus sign instead of the hyphen.
