Sample Operations Sample operations in this manual are indicated by a icon. Unless specifically stated, all sample operations assume that the calculator is in its initial default setup. [. . . ] The maximum allowable height of a calculation formula is two display screens (31 dots × 2). Further input will become impossible if the height of the calculation you are inputting exceeds the allowable limit. · Nesting of functions and parentheses is allowed. Further input will become impossible if you nest too many functions and/or parentheses. If this happens, divide the calculation into multiple parts and calculate each part separately. Note: When you press = and obtain a calculation result, part of the expression you input may be cut off. If you need to view the entire input expression again, press A and then use d and e to scroll the input expression. Using Values and Expressions as Arguments A value or an expression that you have already input can be used as the 7 argument of a function. After you have input , for example, you can make 6 7. it the argument of ', resulting in 6 ' To input 1 + 7 and then change it to 1 + 6 7 ' 6 Math 1+7'6 dddd1Y(INS) ! Math Math As shown above, the value or expression to the right of the cursor after 1Y(INS) are pressed becomes the argument of the function that is specified next. The range encompassed as the argument is everything up to the first open parenthesis to the right, if there is one, or everything up to the first function to the right (' 102, etc. ) 2, This capability can be used with the following functions: ', A, !, 6. E-7 Correcting and Clearing an Expression To delete a single character or function: Move the cursor so it is directly to the right of the character or function you want to delete, and then press Y. To insert a character or function into a calculation: Use d and e to move the cursor to the location where you want to insert the character or function and then input it. · Assigning a remainder calculation result to independent memory (M) will cause only the quotient value to be assigned. For example, assigning the result of the remainder calculation 5÷R2 (5 u 2 S) will result in 2 being assigned to M. Adding a remainder calculation result to or subtracting result from M will add or subtract only the quotient value. · If a ÷R calculation is part of a multi-step calculation, only the quotient is passed on to the next operation. (Example: 10 + 17 u 6 = 10 + 2) · Operation of the F, and e keys is disabled while a remainder division result is on the display. E-11 Cases when Remainder Division becomes Non-remainder Division If either of the following conditions exists when you perform a remainder division operation, the calculation will be treated as normal (non-remainder) division. · When either the dividend or the divisor is a very large value Example: 20000000000 u 17 = Calculated as: 20000000000 ÷ 17 · When the quotient is not a positive integer, or if the remainder is not a positive integer or positive fractional value Example: - 5 u 2 = Calculated as: ­5 ÷ 2 Function Calculations For actual operations using each function, see the "Examples" section following the list below. : is displayed as 3. 141592654, but = 3. 14159265358980 is used for internal calculations. 3. x2, x^, ), x-1 : Powers, square root, and reciprocals. See Note: The following functions cannot be input in consecutive sequence: x2, x^, x-1. If you input 2ww, for example, the final w will be ignored. To 2 input 22 , input 2w, press the d key, and then press w. [. . . ] Note that you should make separate copies of important data before performing these steps. Check the calculation expression to make sure that it does not contain any errors. If the above steps do not correct your problem, press the O key. This will cause the calculator to perform a routine that checks whether calculation functions are operating correctly. [. . . ]
