1. What is Fraction Addition?

Fraction addition is a mathematical operation that combines two fractions into a single fraction. The standard method involves finding a common denominator and then adding the numerators.

2. How Does the Calculator Work?

The calculator uses the 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 denominators, then adds the numerators accordingly, and finally simplifies the result.

3. Importance of Fraction Addition

Details: Adding fractions is fundamental in mathematics and has applications in various fields including engineering, physics, and everyday measurements.

4. Using the Calculator

Tips: Enter all four values (two numerators and two denominators). Denominators must be positive integers. The calculator will provide both fractional and decimal results.

5. Frequently Asked Questions (FAQ)

Q1: Can I add more than two fractions?
A: This calculator handles two fractions at a time. For more fractions, you can chain calculations by using the result as one of the inputs.

Q2: What if my denominators are the same?
A: If denominators are equal, simply add the numerators and keep the denominator: a/b + c/b = (a+c)/b.

Q3: How does simplification work?
A: The calculator finds the greatest common divisor (GCD) of numerator and denominator and divides both by this number.

Q4: Can I use negative numbers?
A: Yes, numerators can be negative but denominators must be positive.

Q5: What about mixed numbers?
A: Convert mixed numbers to improper fractions first (e.g., 2½ becomes 5/2).
