Frequently Asked Questions

What's the difference between DEG and RAD mode?

DEG mode calculates trigonometric functions using degrees (360° in a circle), while RAD mode uses radians (2π in a circle). Most everyday calculations use degrees.

How do I calculate a square root?

Click the √ button, then enter your number and press equals. For example, √144 = 12.

Can I use keyboard input?

Yes! You can type numbers, operators (+, -, *, /), and press Enter to calculate.

How does memory work?

• Use M+ to add the current result to memory
• Use M− to subtract from memory
• Use MR to recall the stored value
• Use MC to clear memory

Tip: This calculator follows standard order of operations (PEMDAS/BODMAS).
