1. What is Fraction Expression Evaluation?

This calculator evaluates mathematical operations between two fractions. It can perform addition, subtraction, multiplication, and division of fractions, providing precise results in decimal form.

2. How Does the Calculator Work?

The calculator evaluates expressions of the form:

Where:

• \( a \) — Numerator of first fraction
• \( b \) — Denominator of first fraction (must be non-zero)
• \( c \) — Numerator of second fraction
• \( d \) — Denominator of second fraction (must be non-zero)
• \( op \) — Mathematical operation (+, -, *, /)

Explanation: The calculator first converts both fractions to decimal form, then performs the specified operation between them.

3. Importance of Fraction Calculations

Details: Fraction operations are fundamental in mathematics, science, engineering, and everyday life. Accurate fraction calculation is essential for precise measurements, ratios, and proportional relationships.

4. Using the Calculator

Tips: Enter numerators and denominators for both fractions, select the operation, and click Calculate. All denominators must be non-zero values.

5. Frequently Asked Questions (FAQ)

Q1: What happens if I enter zero as a denominator?
A: The calculator will display an error message as division by zero is mathematically undefined.

Q2: Can I enter negative numbers?
A: Yes, the calculator accepts negative numbers for numerators and denominators.

Q3: How precise are the results?
A: Results are rounded to 4 decimal places for readability.

Q4: Does the calculator simplify fractions?
A: This version returns decimal results. For simplified fractional results, additional functionality would be needed.

Q5: Can I chain multiple operations?
A: This calculator evaluates one operation between two fractions at a time. For more complex expressions, you would need to perform multiple calculations.
