This webpage is designed to perform basic mathematical calculations using a simple and interactive calculator interface. It includes an input field where users can enter a mathematical expression and a Calculate button to process the entered calculation. The webpage is developed using HTML and JavaScript, providing a straightforward and beginner friendly approach to understanding web development and basic programming logic. The JavaScript function uses string methods such as split to identify different mathematical operators including addition subtraction multiplication and division. Based on the operator entered by the user the program separates the values and performs the corresponding arithmetic operation. The calculated result is then displayed dynamically on the webpage using the innerHTML property. The design focuses on simplicity functionality and ease of use. This project demonstrates important JavaScript concepts such as variables conditional statements string manipulation functions DOM manipulation and basic arithmetic operations. It is a useful beginner level project for learning how JavaScript can process user input and display results interactively on a webpage.
