Rational Number Calculator

Enter fractions (for example: 3/4 or 5/6) and choose an operation.

Mathematics plays a crucial role in academics, engineering, and scientific research. Working with rational numbers, which are numbers that can be expressed as a fraction of two integers, is a common task. Performing operations like addition, subtraction, multiplication, and division manually can often be confusing and prone to mistakes. A Rational Calculator is a digital tool designed to simplify these operations, allowing users to calculate results accurately and instantly.

This project provides a user-friendly interface where users can input rational numbers in fraction form and perform various mathematical operations. The calculator automatically simplifies results, making it highly useful for students, teachers, engineers, and anyone working with rational numbers in practical applications.

Objective

The primary goal of the Rational Calculator is to provide a simple, fast, and accurate tool for performing arithmetic operations on rational numbers. This calculator aims to:

• Perform addition, subtraction, multiplication, and division of rational numbers quickly.
• Provide accurate results without manual computation errors.
• Simplify the results automatically to their lowest terms.
• Offer an intuitive and easy-to-use interface suitable for students, teachers, and professionals.
• Provide a foundation for future enhancements, such as handling mixed numbers or decimal conversion.

Problem Statement

Performing arithmetic operations on rational numbers manually can be challenging, especially for students learning fractions or for professionals dealing with precise calculations. Mistakes in adding, subtracting, multiplying, or dividing fractions are common, particularly when the denominators are different. This can result in incorrect solutions and confusion. Therefore, a Rational Calculator is essential to simplify calculations, reduce errors, and save time.

Scope of the Project

This calculator can be used in educational environments, tutoring sessions, competitive exams, engineering calculations, and scientific research. It can be implemented in web applications, desktop software, and mobile apps. Future enhancements may include support for mixed numbers, decimal conversion, complex rational expressions, and integration with educational platforms. The tool is flexible and can be extended to perform multiple operations at once or handle multiple rational numbers simultaneously.
