Basic arithmetic, fast and clean.
Sometimes you just need a calculator. This one is designed to be fast, clean and completely keyboard-friendly. Every operation available via the buttons can also be triggered from your keyboard — no need to reach for the mouse once you start typing.
Numbers 0–9 and the decimal point work as expected. Use +, −, * and / for operations. Press Enter or = to calculate. Press Escape to clear. Press Backspace to delete the last digit. The calculator handles decimal numbers, negative results, and percentage calculations.
The expression display shows what you've entered before you press equals, helping you catch mistakes. The % button divides the current value by 100 — useful for calculating tips, discounts and tax amounts. The ± button toggles the sign of the current number.
For more complex calculations involving scientific functions, logarithms or trigonometry, consider using your operating system's built-in scientific calculator mode.
