A few reminders about when to use them:

  • % — Don’t use it except in tables and infographics. In text, spell out “percent.” (That’s one word, not “per cent” — unless you’re in Britain.)
  • $ — Use the dollar sign or the D word (200 dollars, $200) but not both together ($200 dollars). The sign is preferable, except in very informal usage (“I feel like a million dollars!”).
  • & — Use only when it’s part of a proper name (e.g., Johnson & Johnson). Otherwise spell out “and.”
