1. What is the Negative and Positive Number Calculator?

This calculator computes the result of subtracting a negative number from a positive number, which effectively adds their absolute values. It's useful for financial calculations, physics problems, and other scenarios involving opposite signed numbers.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( pos \) — Any positive number (≥0)
• \( neg \) — Any negative number (≤0)

Explanation: Subtracting a negative number is equivalent to adding its absolute value to the positive number.

3. Importance of This Calculation

Details: This calculation is fundamental in accounting (net calculations), physics (vector operations), and temperature differentials. Understanding how positive and negative numbers interact is crucial for many STEM fields.

4. Using the Calculator

Tips: Enter any positive number in the first field and any negative number in the second field. The calculator will compute the result of subtracting the negative from the positive.

5. Frequently Asked Questions (FAQ)

Q1: Why does subtracting a negative give a positive result?
A: Subtracting a negative is equivalent to adding a positive. For example, 5 - (-3) = 5 + 3 = 8.

Q2: Can I use decimals or fractions?
A: Yes, the calculator accepts any real numbers as long as the first is positive and the second is negative.

Q3: What if I enter a positive in the negative field?
A: The calculator will still compute a result, but it won't follow the intended operation of subtracting a negative from a positive.

Q4: Where is this calculation used in real life?
A: Common applications include financial net calculations, temperature differences, elevation changes, and electrical charge calculations.

Q5: How precise are the results?
A: Results are precise to 4 decimal places, suitable for most practical applications.
