[. . . ] The display comprises the entry line, the result line, and indicators. Entries begin on the left; those with more than 15 digits scroll to the left. Press [ ] and [ ] to move the cursor through an entry. However, whenever you input the 89th digit of any calculation, the cursor changes from " " to " " to let you know memory is running low. [. . . ] In that case, please make necessary corrections before executing the calculation again. After execution is completed, pressing [ ] or [ ] key will display the operation executed. You can continue moving the cursor by [ ] or [ ] to display previous input steps and editing values or commands for subsequent execution. The operation records in Memory are cleared each time when you turn off the calculator, press [ ON ] key, perform a "reset", change display format or calculation mode. When the memory is full, the oldest calculation records are deleted automatically to make room for the new ones. Memory variable The calculator has seven memory variables for repeated use -- A, B, C, D, M, X, Y. You can store a real number in any of the seven memory variables. [ ALPHA ] + " memory variable " lets you insert the applicable variables in a calculation. Running memory You should keep the following rules in mind when using running memory. Press [ M+ ] to add a result to running memory and the " M " indicator appears when a number is stored in the memory. Recalling from running memory by pressing [ RCL ] [ M ] key does not affect its contents . Be sure to enter [ x ] between the [ ) ] and [ x10 ] in Example 11. You can use this key sequence to calculate percentages, add-ons, discounts, and percentage ratios. Fixed Decimal Point Notation To specify the number of decimal places, press [ 2nd ] [ SET UP ] [ 6 ] and then a value indicating the number of places ( 0~9 ). Values are displayed rounded off to the place specified. Scientific Notation Scientific notation expresses numbers with one digit to the left of the decimal and the appropriate power of 10. To select scientific notation, press [ 2nd ] [ SET UP ] [ 7 ], and then a value (0~9) to specify the number of decimal digits. Values are displayed rounded off to the place specified. It is retained even after the power is turned off. Once a numeric value or numeric expression is entered and [ M+ ], [ 2nd ] [ M­ ], [ RCL ], [ 2nd ] [ STO ] or [ = ] is pressed, the result is stored by this function. (Note) : Even if execution of a calculation results in an error, however, Answer memory retains its current value. The calculator can calculate common and natural logarithms, and x exponentiation using [ log ], [ ln ], [log a b], [ 2nd ] [ 10 ], and [ 2nd ] x [ e ]. [. . . ] Calculates the number of possible combinations of n items taken r at a time. The calculator also provides reciprocal ( [ x ] ), square root ( [ ] ), cubic root ( [ 2nd ] [ 3 ] ), universal root ( [ 2nd ] [ X ] ), square 2 3 y ( [ x ] ), cubic ( [ x ] ), and exponentiation ( [ x ] ) functions. Abs RND Generates the absolute value of a real number Generates the rounding value of a given number A Multi-statement is a number of individual statements grouped together by display result commands () for sequential execution. When execution reaches the end of a statement followed by (), execution stops and an intermediate result with a " Disp " icon appears on the display. [. . . ]
