1. What is Fraction Addition?

Fraction addition is a mathematical operation that combines two fractions into a single fraction. The operation requires finding a common denominator before adding the numerators.

2. How Does the Calculator Work?

The calculator uses the standard fraction addition formula:

\[ \frac{a}{b} + \frac{c}{d} = \frac{ad + bc}{bd} \]

Where:

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

3. Importance of Fraction Operations

Details: Fraction operations are fundamental in mathematics, used in measurements, ratios, probabilities, and many real-world applications like cooking, construction, and finance.

4. Using the Calculator

Tips: Enter all four values (two numerators and two denominators). Denominators must be positive integers. The calculator will show both the raw result and simplified form.

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 the 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 enter negative numbers?
A: Yes, numerators can be negative, but denominators must remain positive.

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

Q5: Does this work for subtraction too?
A: Yes, simply enter negative values for the numerator you want to subtract.
