1. What is the Fraction Calculator?

This calculator computes the result of adding two fractions where the first fraction is negative. It handles both positive and negative numbers in the numerators and denominators.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( a \) — First numerator (can be positive or negative)
• \( b \) — First denominator (must be positive)
• \( c \) — Second numerator (can be positive or negative)
• \( d \) — Second denominator (must be positive)

Explanation: The calculator first converts the first fraction to negative, then adds it to the second fraction, handling all possible sign combinations correctly.

3. Importance of Fraction Calculations

Details: Understanding fraction operations with negative numbers is crucial for algebra, physics, chemistry, and many real-world applications involving ratios and proportions.

4. Using the Calculator

Tips: Enter all four values (a, b, c, d). Denominators cannot be zero. The calculator will automatically handle the negative sign for the first fraction.

5. Frequently Asked Questions (FAQ)

Q1: What if I want the first fraction to be positive?
A: Simply enter a negative value for 'a' to make the first fraction positive.

Q2: Can I enter decimal numbers?
A: Yes, the calculator accepts both integers and decimal numbers.

Q3: What happens if I enter zero for a denominator?
A: The calculator will not accept zero denominators as division by zero is undefined.

Q4: How precise are the results?
A: Results are displayed with 4 decimal places for accuracy.

Q5: Can I use this for subtracting fractions?
A: Yes, simply enter a negative value for 'c' to perform subtraction.
