1. What is Fraction Calculator?

The Fraction Calculator performs addition and subtraction of fractions, providing results in simplified form. It helps with mathematical operations involving fractions in everyday calculations.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( a \) — Numerator of first fraction
• \( b \) — Denominator of first fraction
• \( c \) — Numerator of second fraction
• \( d \) — Denominator of second fraction
• \( \pm \) — Addition or subtraction operation

Explanation: The calculator finds a common denominator, performs the operation on numerators, and simplifies the result by dividing numerator and denominator by their greatest common divisor (GCD).

3. Importance of Fraction Operations

Details: Fraction operations are fundamental in mathematics, used in cooking, construction, science, and financial calculations where precise measurements are required.

4. Using the Calculator

Tips: Enter numerators and denominators (must be positive integers), select operation (addition or subtraction). The calculator will show the result in simplest form.

5. Frequently Asked Questions (FAQ)

Q1: Can I use negative numbers?
A: The calculator currently only accepts positive integers for denominators. Numerators can be negative.

Q2: What if I enter a zero denominator?
A: The calculator requires denominators to be positive integers (minimum value of 1).

Q3: How is the fraction simplified?
A: The calculator divides both numerator and denominator by their greatest common divisor (GCD).

Q4: Can I see the calculation steps?
A: Yes, the calculator shows each step of the operation including finding common denominator and simplification.

Q5: Does it handle mixed numbers?
A: Currently it only handles simple fractions. Convert mixed numbers to improper fractions first.
