Frequently Asked Questions

■ How can I perform input and display results the same way I did on a model that does not have Natural Textbook Format?

→ Perform the following key operation: (SETUP)(LineIO). See "Configuring the Calculator Setup" for more information.

■ 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" for the procedure.

■ 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.

■ 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).

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

→ Perform the following key operation: (CLR)(Setup)(Yes).

■ 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.
