Frequently Asked Questions
k 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: 1N(SETUP) 2(LineIO). See
“Configuring the Calculator Setup” on page E-5 for more information.
k 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-13 for the procedure.
k What is the difference between Ans memory, PreAns 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.
PreAns Memory: Stores the result of calculation before the last one.
PreAns memory can be used only in the COMP Mode.
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 Mode or TABLE
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
