1. What is Decimal Addition and Subtraction?

Decimal addition and subtraction are fundamental arithmetic operations that involve numbers with decimal points. These operations follow the same principles as whole number operations but require careful alignment of decimal points.

2. How Does the Calculator Work?

The calculator performs the simple operation:

Where:

• \( a \) — First decimal number
• \( \pm \) — Addition or subtraction operation
• \( b \) — Second decimal number

Explanation: The calculator aligns the decimal points and performs the operation, handling up to 4 decimal places with proper rounding.

3. Importance of Decimal Operations

Details: Decimal operations are essential in everyday life, including financial calculations, measurements, scientific computations, and statistical analysis. Accuracy in decimal operations is crucial for precise results.

4. Using the Calculator

Tips: Enter two decimal numbers, select the operation (addition or subtraction), and click calculate. The calculator will display the result with proper decimal alignment and rounding.

5. Frequently Asked Questions (FAQ)

Q1: How many decimal places does the calculator support?
A: The calculator supports up to 4 decimal places and rounds the result appropriately.

Q2: Can I use negative numbers with this calculator?
A: Yes, the calculator supports both positive and negative decimal numbers.

Q3: What happens if I enter non-decimal numbers?
A: The calculator will automatically treat whole numbers as decimals (e.g., 5 becomes 5.0000).

Q4: How does the calculator handle rounding?
A: The calculator uses standard rounding rules, rounding to the nearest value at the 4th decimal place.

Q5: Is there a limit to the size of numbers I can calculate?
A: While there's no strict limit, extremely large numbers may lose precision due to floating-point representation limitations.
