1. What is Fraction Addition?

Fraction addition combines two fractions into a single fraction. The basic rule is to find a common denominator, then add the numerators while keeping the denominator the same.

2. How Does the Calculator Work?

The calculator uses the standard fraction addition formula:

Where:

• \( a \) — Numerator of first fraction
• \( b \) — Denominator of first fraction
• \( c \) — Numerator of second fraction
• \( d \) — Denominator of second fraction

Explanation: The calculator first finds a common denominator by multiplying the two denominators, then adds the numerators appropriately, and finally simplifies the result if possible.

3. Importance of Fractions

Details: Fractions are fundamental in mathematics and appear in everyday situations like cooking, measurements, and financial calculations. Understanding how to add fractions is essential for more advanced math concepts.

4. Using the Calculator

Tips: Enter whole numbers for all four fields (a, b, c, d). Denominators (b and d) must be positive integers. The calculator will automatically simplify the result if possible.

5. Frequently Asked Questions (FAQ)

Q1: What if I enter a zero denominator?
A: The calculator requires denominators to be positive integers. Division by zero is undefined.

Q2: How does simplification work?
A: The calculator finds the greatest common divisor (GCD) of the numerator and denominator and divides both by this number.

Q3: Can I add more than two fractions?
A: This calculator handles two fractions at a time. For more fractions, add them two at a time.

Q4: What about mixed numbers?
A: Convert mixed numbers to improper fractions first (e.g., 2½ becomes 5/2).

Q5: Can I use negative numbers?
A: Yes, numerators can be negative, but denominators must remain positive.
