An opening parenthesis needs a closing parenthesis. Catch the bachelors. A footnote reference mark or a first reference to a table or an illustration is termed a callout. Be sure a footnote begins on the same page as its callout. Be sure a table or illustration follows its callout as soon as possible.
Numbers can speak louder than words.
Misprints in figures can be catastrophic. Take care with dollar figures and numbers in dates, statistics, tables or technical text. Read all numerals character by character. Two plus two is twenty-two. The simplest math can go wrong.
