Frequently asked questions
Can I use my keyboard instead of clicking buttons?
Yes. Type digits and operators directly, press Enter or = for the result, and use Backspace to correct a mistake — often faster than clicking the on-screen keypad.
What operations does the simple calculator support?
The four basic operations — addition, subtraction, multiplication and division — plus percentages and sign changes. For trigonometry, powers, roots and logarithms, use the scientific calculator instead.
Why use an online calculator instead of my phone?
When you are already working in a browser, it saves switching devices or hunting for an app. It loads instantly, works on any device, and everything is computed on your machine with nothing sent to a server.
