1. What is This Calculator?

This is a simple calculator that performs basic arithmetic operations (addition, subtraction, multiplication, and division) on two numbers. It demonstrates the functionality that could be implemented in a Java GUI application.

2. How Does the Calculator Work?

The calculator performs operations based on the following formulas:

Addition: \[ Result = Num1 + Num2 \]
Subtraction: \[ Result = Num1 - Num2 \]
Multiplication: \[ Result = Num1 \times Num2 \]
Division: \[ Result = \frac{Num1}{Num2} \] (when Num2 ≠ 0)

Explanation: The calculator takes two numbers and performs the selected arithmetic operation, displaying the result.

3. Importance of Simple Calculations

Details: Basic arithmetic operations are fundamental to all computing applications. Understanding these operations is essential for programming and algorithm development.

4. Using the Calculator

Tips: Enter two numbers, select an operation, and click "Calculate" to see the result. For division, ensure the second number is not zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the precision of the calculator?
A: The calculator uses floating-point arithmetic with a precision of 4 decimal places.

Q2: Can I use negative numbers?
A: Yes, the calculator supports negative numbers for all operations.

Q3: What happens if I divide by zero?
A: The calculator will display "Undefined (division by zero)" as the result.

Q4: How would this be implemented in Java GUI?
A: Similar logic would be used in action listeners for buttons in a Java Swing or JavaFX application.

Q5: Are there limitations to this calculator?
A: This is a basic calculator for demonstration purposes. For more complex calculations, a scientific calculator would be needed.
