1. What is the Fraction Calculator?

The Fraction Calculator performs basic arithmetic operations (addition, subtraction, multiplication, division) with fractions. It provides results in simplified form, showing both the calculation and the simplified answer.

2. How Does the Calculator Work?

The calculator uses standard fraction arithmetic rules:

Where operations follow these rules:

• Addition/Subtraction: \(\frac{a}{b} \pm \frac{c}{d} = \frac{ad \pm bc}{bd}\)
• Multiplication: \(\frac{a}{b} \times \frac{c}{d} = \frac{ac}{bd}\)
• Division: \(\frac{a}{b} \div \frac{c}{d} = \frac{ad}{bc}\)

Explanation: The calculator automatically simplifies results by dividing numerator and denominator by their greatest common divisor (GCD).

3. Supported Operations

Details: The calculator supports all four basic arithmetic operations with proper and improper fractions.

4. Using the Calculator

Tips: Enter numerators and denominators (must be non-zero for denominators). Select the operation and click Calculate. Results show both the calculation and simplified form.

5. Frequently Asked Questions (FAQ)

Q1: Can I use negative numbers?
A: Yes, the calculator supports negative fractions in both numerators and denominators.

Q2: What if I enter zero as denominator?
A: The calculator requires denominators to be non-zero (division by zero is undefined).

Q3: How are mixed numbers handled?
A: Enter them as improper fractions (e.g., 1½ as 3/2).

Q4: Does it show decimal equivalents?
A: Currently it shows only fractional results, but you can divide numerator by denominator for decimal form.

Q5: What's the maximum number size?
A: Very large numbers may cause calculation errors due to PHP integer limits.
