Edita's Standard Calculator gives you an instant, reliable arithmetic calculator that works in any browser tab without installing an app or switching to your phone's calculator. It handles the everyday operations everyone needs: addition, subtraction, multiplication, division, percentage calculations, and sign changes — with a clean interface and keyboard support.
Features
- Full keyboard support — type calculations without touching the mouse
- Percentage key for quick percentage calculations
- Calculation history so you can review recent operations
- Works offline once the page is loaded
When a Browser Calculator Is Useful
When you're in the middle of working in another browser tab — a spreadsheet, an invoice, a shopping cart — switching to a phone calculator breaks your focus. A browser-based calculator keeps everything in one window. It's also ideal for shared or borrowed computers where installing a calculator app isn't an option.
