│ The calculator uses Reverse Polish Notation. To use RPN, it is │
│ necessary to enter the two numbers to be operated on and then enter │
│ the operation (+ - * ÷). The + - * / keys enter numbers into the │
│ calculator entry register and add, subtract, multiply or divide the │
│ numbers that are in the entry register and the result register. │
│ For example: │

││ - ││ 5 │ 25.00│ in the entry register and may │
││ * ││ 5 │ 125.00│ be used without entering it │
││ / ││ 5 │ 25.00│ for each calculation.) │
