Calculate function

square root

• Tap "√□", "9", "="

• In this case, even if you tap the "Natural number display, Real number display" button, "3" remains.

Trigonometric function(sin)

• Confirm that the angle unit is "DEG". If it is "RAD", tap "RAD" to switch to "DEG"
• Tap "sin", "1", "5", ")", "=".
• "sin(15)=" appears in the calculation frame.
• "√6-√2/4" is displayed in the answer box.
• When you tap "Natural display ⇔ Real number display", "0.2588190451" is displayed in the answer frame.

Calculations with parentheses

• Tap "9", "÷", "3", "(", "1", "+", "2", ")", "=".
• "9÷3(1+2)=" is displayed in the calculation frame.
• A "1" will appear in the answer box.
• If you omit the multiplication sign, the calculation will take precedence over the usual "x" and "÷", so the calculation will be "9÷(3×(1+2))".
• If you want to calculate "9 ÷ 3 x (1 + 2) = 9", you can change it on the setting screen.
