Parentheses
You need to use parentheses to enclose arguments for
functions, such as SIN(45). You can omit the final parenthesis
at the end of an edit line. The calculator inserts it
automatically.
Parentheses are also important in specifying the order of
operation. Without parentheses, the HP 39G/40G calculates
according to the order of algebraic precedence (the next
topic). Following are some examples using parentheses.
