Lesson 3.3: Parentheses
A mathematical expression can be enclosed in parentheses to indicate that the expression should be evaluated first. Parentheses are also used in math to group items together or to indicate that the numbers are linked in some way. Parentheses are used in pairs as an opening parenthesis and a closing parenthesis. The opening parenthesis is formed with a dot five prefix, and a dots one two six root. The closing parenthesis is formed with a dot five prefix followed by a dots three four five root. Follow print for use of parentheses. There is usually no space between the parenthesis and the items associated with them.
Parentheses terminate numeric mode. The numeric indicator is required before a numeral that immediately follows an opening or closing parenthesis.
