About this Calculator

This basic calculator is a web-based tool designed to do simple arithmetic operations like addition, subtraction, multiplication, and division. It looks and behaves just like a regular hand-held calculator, and it’s perfect for quick math calculations right in your web browser.

Programmed using JavaScript, HTML and CSS, the calculator has buttons for the digits 0–9, basic operators like +, -, ×, ÷, an all clear key, and an equals key. Calculations are processed locally in your browser using JavaScript, so the webpage does not need to interact with a server.

This web-based calculator is lightweight, mobile-friendly, and you can operate it with a mouse, number pad, keyboard, or touch screen on any device.
