Frequently Asked Questions
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, 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.
■ 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.
Example: (sin 30) + 15 (Angle Unit: Deg)
- Older (S-V.P.A.M.) Model:
- 3015 15.5
Natural Textbook Display Model:
- (LineIO)
- 3015 15.5
Failure to press here as shown below will result in calculation of sin 45.
