The HP 12c financial calculator allows accountants to quickly make complex calculations, such as the time value of money problems. The keys on a financial calculator differ from those on a scientific calculator. Do not be alarmed by the differences, as the HP 12c calculator will still perform the normal math functions of a scientific calculator, such as exponents. This allows the user to make both finance calculations and more conventional calculations. As an example, suppose you want to calculate 2^4.
Press "f" and then "RPN" to put the calculator in Reverse Polish Notation.
Type the base number. In the example, type "2."
Type the exponent. In the example, it would be "4."
Press the "y^x" button. In the example, the calculator will display "16."
