Using parentheses
Since all calculations inside parentheses are
completed first, it is sometimes important to place
a portion of an expression inside parentheses.
Example: Multiply 4*1+2; then multiply 4*(1+2).
Press Result
4 ¯ 1 Ã 2

4 ¯ £ 1 Ã 2 ¤

Note: The closing parenthesis
¤
is optional. The operation will be
completed if you omit it. The exception to this rule occurs when
there is another operation following the parenthetical operation. In
this case, you must include the closing parenthesis.
