1. What is This Calculator?

This calculator performs fraction calculations with negative numbers and decimals using the formula: -(a/b) + decimal. It handles all real numbers except division by zero.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( a \) — Numerator (can be positive or negative)
• \( b \) — Denominator (can be positive or negative, but not zero)
• \( decimal \) — Any decimal number to add (can be positive or negative)

Explanation: The calculator first divides the numerator by the denominator, negates the result, then adds the decimal value.

3. Handling Negative Numbers and Decimals

Details: The calculator properly handles all combinations of positive and negative values for both the fraction components and the decimal addition.

4. Using the Calculator

Tips: Enter any real numbers for numerator and decimal. Denominator can be any real number except zero. The calculator will handle negative values automatically.

5. Frequently Asked Questions (FAQ)

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

Q2: How many decimal places does the calculator show?
A: Results are rounded to 4 decimal places for clarity.

Q3: Can I use very large numbers?
A: Yes, but extremely large numbers may be subject to floating-point precision limitations.

Q4: How are negative values handled in the fraction?
A: The negative sign applies to the entire fraction result before the decimal is added.

Q5: Can I use this for complex numbers?
A: No, this calculator only works with real numbers.
