1. What is the Negative Number Calculator?

The Negative Number Calculator computes the additive inverse of any given number. This simple operation is fundamental in mathematics and has applications across various fields.

2. How Does the Calculator Work?

The calculator uses the negative number formula:

Where:

• \( num \) — Any real number (positive, negative, or zero)

Explanation: The calculator simply changes the sign of the input number. If the input is positive, the result is negative, and vice versa.

3. Importance of Negative Numbers

Details: Negative numbers are essential in mathematics, physics, engineering, finance, and many other fields. They represent values below zero, debts, opposite directions, and more.

4. Using the Calculator

Tips: Enter any numerical value in the input field. The calculator will return the negative (additive inverse) of that number.

5. Frequently Asked Questions (FAQ)

Q1: What happens if I input zero?
A: The negative of zero is still zero, since -0 = 0.

Q2: What if I input a negative number?
A: The calculator will return the positive version of that number (the negative of a negative is positive).

Q3: Can I use decimal numbers?
A: Yes, the calculator works with any real number, including decimals and fractions.

Q4: What's the practical use of this calculation?
A: This operation is used in temperature conversions, financial calculations (debts/credits), vector mathematics, and many other applications.

Q5: Does this calculator handle complex numbers?
A: No, this calculator only works with real numbers. For complex numbers, the negation operation would affect both the real and imaginary parts.
