In a rapidly evolving technological landscape, the necessity for accessible and user-centric solutions for daily activities has become increasingly pronounced. This project responds to this imperative by introducing a sophisticated HTML calculator, engineered with contemporary web technologies such as Bootstrap and jQuery. Functioning as a versatile hub for fundamental arithmetic computations, the calculator is designed to offer users an intuitive and frictionless experience. By harnessing the capabilities of web development, the project endeavors to bolster the accessibility and utility of computational tools across various domains, catering to the diverse needs of modern users.
