About This Calculator
This is a fast, lightweight, and fully responsive web calculator designed to handle your day-to-day arithmetic. Whether you are browsing on a mobile phone, tablet, or PC, it automatically scales to give you the best experience.
How to Use It:

- Smart Corrections: If you accidentally type an operator at the very end of your math and hit equals, the system ignores it and executes your equation flawlessly without throwing an error!
