I 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

Older (S-VPAM) Model: Q 30  15 

15.5

Natural Textbook Display Model: 1 Q 30  15  15.5

Failure to press  here as shown below will result in calculation of sin 45.
