Enter numbers either by clicking on the buttons or using the keyboard (note: to use a numeric keypad make sure Num Lock is on). To enter a number in exponential format, enter the mantissa, followed by the EXP key, then +/- if required, then the exponent. To use the arithmetic functions, click their buttons. If the function is unary (i.e. acts on one number, e.g. 1/x) the display is updated to the result.
