Input Method
- Simple specifies an infix order where the operations are performed in the order they are entered, for example, entering 2 + 3 * 5 = yields the result of 25
- Precedence also specifies an infix order where binary operations are performed before multiplication and division which are performed before addition and subtraction reducing the need for using parentheses, for example, 2 + 3 * 5 = yields the result of 17
- RPN (Reverse Polish Notation) specifies a postfix order where the operands are entered before the operation, for example, 2 Enter 3 + 5 * yields 25 and 2 Enter 3 Enter 5 * + yields 17
- The input method can be specified at any time in the Preferences dialog
