k 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. 
k What is the key operation to take me from the STAT, EQN, or BASE-N 
Mode to a mode where I can perform arithmetic calculations? 
     Press   N1(COMP). 
k How can I return the calculator to its initial default settings? 
      Perform the following operation:   19(CLR)  1(Setup)  =(Yes)
k 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    v
    Older (S-VPAM) Model:    s 30  + 15  = 15.5
     Natural Textbook Display Model:   b s 30  )+ 15  = 15.5
     Failure to press  ) here as shown below will result in calculation of sin 45. 
        s 30  + 15  =   0.7071067812
