Using the Calculator function
The built-in calculator in the Electronic Dictionary can perform twelve-digit
arithmetic calculations with memory function. To access the Calculator function,
press
a.
Prior to initiating calculations
• Before performing any calculation, press @ @ b to clear the
memory and the display.
• To start a calculation with a negative number, place a subtraction sign by
pressing - at the beginning of the calculation.
• If you wish to correct a wrong entry, press ! and re-enter the figure.
• In the calculation examples found in this section, indications and icons that may
appear on the screen (‘=’, ‘M+’, ‘M-’, ‘+’, ‘-’, ‘x’, and ‘÷’) are abbreviated or are not
shown. These icons appear to show you the interim result of calculations. For
example, the ‘=’ icon appears on the screen when
= or % is pressed, while
icons such as ‘M+’ and ‘+’ appear after each corresponding key has been
pressed.
• An ‘M’ is shown when a value other than 0 is put in the memory. To clear the
content of the memory, press @ twice. Note that the pressing of $ or #
also functions as =.
• Press to enter ‘=’. To input ‘.’ (decimal point), press .
• An error message ‘E’ is displayed if:
• the integer section of a calculation result exceeds 12 digits
• the memory exceeds 12 digits
• an attempt is made to divide a number by zero.
Press ! to clear the error condition.

34
+ 57 = The second figure (57)
45 = becomes the constant.
(Subtraction and division are performed in
the same way as above.)
68 * 25 = The first figure (68)
40 = becomes the constant.
200 * 10 %
9 / 36 %
200 + 10 %
500 - 20 %
