What operations does the online calculator support?

Our calculator supports basic arithmetic (addition, subtraction, multiplication, division), advanced functions (square, square root, percentage, reciprocal), memory operations (store, recall, add to memory, subtract from memory), and complex expressions using parentheses.

How do I use the memory functions?

Use MC to clear memory, MR to recall stored value, M+ to add current value to memory, M- to subtract from memory, and MS to store current value. The memory panel shows all stored values and can be toggled on/off.

Can I save my calculation history?

Yes, all calculations are automatically saved to your browser's local storage. You can view your complete calculation history, reuse previous calculations, or copy results. Your history remains private and never leaves your device.

What is the difference between basic and scientific modes?

Basic mode includes standard arithmetic operations. Scientific mode adds advanced functions: square (x²), square root (√x), percentage (%), reciprocal (1/x), and parentheses for complex expressions. You can toggle between modes using the switch button.

Can I copy and share calculation results?

Yes, you can copy any result to clipboard using the copy button, or share complete calculations including expressions and results using the share functionality. This works across all modern browsers and devices.

Is this calculator suitable for students and professionals?

Absolutely! The calculator is designed for both educational and professional use. Students can use it for homework and exams practice, while professionals can use it for financial calculations, engineering math, and general office calculations.

Does the calculator handle complex mathematical expressions?

Yes, the calculator supports complex expressions using parentheses and operator precedence. You can build multi-step calculations and the calculator follows standard mathematical order of operations (PEMDAS/BODMAS).

What happens if I make an error in my calculation?

The calculator provides clear error messages for invalid operations (like division by zero). You can use CE (Clear Entry) to delete the last entry, or C (Clear) to reset the entire calculation. The interface gives immediate feedback on any issues.
