A Inputting Scientifi c Functions with Parentheses (sin, cos, ',
etc.)
Your calculator supports input of the scientifi c functions with parentheses shown below.
Note that after you input the argument, you need to press
) to close the parentheses.

Note
Some functions require a different input sequence when using natural input. For more
information, see “Inputting Calculation Expressions Using Natural Display” on page 17.
A Omitting the Multiplication Sign
You can omit the multiplication sign in the following cases.
• Immediately before an open parenthesis: 2 × (5 + 4)
• Immediately before a scientifi c function with parentheses: 2 × sin(30), 2 ×
'(3)
• Before a prefi x symbol (excluding the minus sign): 2 × h123
• Before a variable name, constant, or random number: 20 × A, 2 ×
π , 2 × i
A Final Closed Parenthesis
You can omit one or more closed parentheses that come at the end of a calculation,
immediately before the
w key is pressed.
Example: (2 + 3) (4 − 1) = 15
b
(2+3)

A Calculation Expression Wrapping (Linear Display)
When using linear display, calculation expressions that are longer than 16 characters
(numbers, letters, and operators) are wrapped automatically to the next line.
Example: 123456789 + 123456789 = 246913578
b
123456789+
123456789E
