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. If you input 2 , for example, the final will be ignored. To 2 2 , input 2 , press the key, and then press ( ). input 2 Pol, Rec : Pol converts rectangular coordinates to polar coordinates, while Rec converts polar coordinates to rectangular coordinates. Specify the angle unit before Pol(x, y) = (r, ) Rec(r, ) = (x, y) performing calculations. The calculation result for r and and for x and y are each assigned respectively to variables X and Y. Calculation result is displayed in the range of -180° Rectangular Polar 180°. Coordinates (Rec) Coordinates (Pol) x2, x3, x , x !See 9. Abs : Absolute value function. Note that the input method is different depending upon whether you are using Natural Display or Linear Display. Ran# : Generates a 3-digit pseudo random number that is less than 1. The result is displayed as a fraction when Natural Display is selected. [. . . ] If the above steps do not correct your problem, press the key. 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. For details about initialized settings, see "Configuring the Calculator Setup". [. . . ]
