Frequently Asked Questions

I

 How can I perform input and display results the same way I did on a 

model that does not have Natural Textbook Display?

  Perform the following key operation: 

(SETUP)

(LineIO). See 

“Configuring the Calculator Setup” on page E-5 for more information. 

I

 How can I change a fraction form result to decimal form? 

  How can I change a fraction form result produced by a division 

operation to decimal form?

  See “Toggling Calculation Results” on page E-9 for the procedure. 

I

 What is the difference between Ans memory, independent memory, 

and variable memory? 

Each of these types of memory acts like “containers” for temporary storage 
of a single value. 

 Ans 

Memory:

 Stores the result of the last calculation performed. Use this 

memory to carry the result of one calculation on to the next. 

 Independent 

Memory:

 Use this memory to totalize the results of multiple 

calculations. 

 Variables:

 This memory is helpful when you need to uses the same value 

multiple times in one or more calculations. 

I

 What is the key operation to take me from the STAT Mode or TABLE 

Mode to a mode where I can perform arithmetic calculations? 

 Press 

(COMP).

I

 How can I return the calculator to its initial default settings? 

  Perform the following operation: 

(CLR)

(Setup)

(Yes)

I

 When I execute a function calculation, why do I get a calculation result 

that is completely different from older CASIO calculator models? 

  With a Natural Textbook Display model, the argument of a function that 

uses parentheses must be followed by a closing parenthesis. Failing to 
press 

 after the argument to close the parentheses may cause unwanted 

values or expressions to be included as part of the argument. 

  Example: (sin 30) + 15
