Replay While a calculation result is on the display, you can press the expression you used for the previous calculation. 4 × 3 + 2. 5 = 14. 5 4 × 3 - 7. 1 = 4. 9 4 (Continuing) 3 or to edit 2. 5 7. 1 14. 5 4. 9 Note: If you want to edit a calculation when the indicator is on the right side of a calculation result display (see "Reading the Display"), press and then use and to scroll the calculation. Answer Memory (Ans) The last calculation result obtained is stored in Ans (answer) memory. Ans memory contents are updated whenever a new calculation result is displayed. To divide the result of 3 4 by 30 3 (Continuing) 4 30 123 + 456 = 579 789 ­ 579 = 210 (Continuing) 123 456 789 Variables (A, B, C, D, E, F, X, Y) Your calculator has eight preset variables named A, B, C, D, E, F, X, and Y. You can assign values to variables and also use the variables in calculations. To assign the result of 3 + 5 to variable A 3 5 To multiply the contents of variable A by 10 (Continuing) To recall the contents of variable A To clear the contents of variable A (STO) (A) 8 80 (A) 10 (A) (A) (Continuing) 0 (STO) 8 0 E-12 Independent Memory (M) You can add calculation results to or subtract results from independent memory. The "M" appears on the display when there is any value other than zero stored in independent memory. To clear the contents of M To add the result of 10 5 to M 0 (Continuing) (STO) 10 5 (M) 0 50 15 35 To subtract the result of 10 + 5 from M (Continuing) To recall the contents of M 10 5 (M­) (M) (Continuing) Note: Variable M is used for independent memory. Clearing the Contents of All Memories Ans memory, independent memory, and variable contents are retained even if you press , change the calculation mode, or turn off the calculator. Perform the following procedure when you want to clear the contents of all memories. (CLR) (Memory) (Yes) Prime Factorization In the COMP Mode, you can factor a positive integer up to 10 digits into prime factors up to three digits. To perform prime factorization on 1014 1014 (FACT) When you perform prime factorization on a value that includes a factor that is prime number with more than three digits, the part that cannot be factored will be enclosed in parentheses on the display. To perform prime factorization on 4104676 (= 22 (FACT) Any one of the following operations will exit prime factorization result display. · Using the setup menu to change the angle unit setting (Deg, Rad, Gra) or the display digits setting (Fix, Sci, Norm). Note: · You will not be able to execute prime factorization while a decimal value, fraction, or negative value calculation result is displayed. · You will not be able to execute prime factorization while the result of a calculation that uses Pol, Rec is displayed. 10132) E-13 C Function Calculations For actual operations using each function, see the "Examples" section following the list below. Input a function from the menu that appears when you perform the following key operation: (DRG ). Note that the input method is different depending upon whether you are using Natural Display or Linear Display. Use the key also 10 is the default setting if you do not input anything for a. The can be used for input, but only while Natural Display is selected. See 6. = 3. 14159265358980 is used for e : e is displayed as 2. 718281828, but e = 2. 71828182845904 is used for , , , x-1 : Powers, power roots, and reciprocals. Note that , , and are different depending upon the input methods for x , whether you are using Natural Display or Linear Display. [. . . ] Check the calculation expression to make sure that it does not contain any errors. C E-28 2. Make sure that you are using the correct mode for the type of calculation you are trying to perform. This will cause the calculator to perform a routine that checks whether calculation functions are operating correctly. If the calculator discovers any abnormality, it automatically initializes the calculation mode and clears memory contents. [. . . ]
