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   B
  Older (S-VPAM) Model:    Q 30  15  
15.5
  Natural Textbook Display Model:  1 Q 30  15   15.5
 Failure to press  here as shown below will result in calculation of sin 45.
