Q & A
How can I insert and display results in the same way I used for a model that did
not have a Natural View?
Perform the following key operation: SHIFT + MODE (SETUP) + 2 (LinelO).
What is the difference between the memory of the last result, the independent
memory and the memory of the variable?
Each of these types of memory acts as a "stack" for temporarily storing an individual
value.
Last Result Memory: Stores the result of the last calculation. Use this memory to transfer
the result of one calculation to another.
Independent memory: Use this memory to summarize the results of multiple counting.
Variable memory: This memory is useful if you need to use the same value multiple
times in one or more calculations.
When I perform a function calculation, why do I get a calculation result that is
completely different from the older CASIO calculator model?
For a Natural View model, the argument of a function that uses parentheses must be
followed by closed parentheses. Failure to press parentheses after an argument to
enclose parentheses can cause unwanted values or expressions to be included as part
of the argument.
