# Basic Web Calculator

This is a simple web-based calculator that performs basic arithmetic operations: addition, subtraction, multiplication, and division. It is built using HTML, and JavaScript.

## Features

- **Addition**: Adds two numbers.

- **Subtraction**: Subtracts the second number from the first number.

- **Multiplication**: Multiplies two numbers.

- **Division**: Divides the first number by the second number (handles division by zero).

## Usage

1. Enter the first number in the Number 1 input field.

2. Enter the second number in the Number 2 input field.

3. Click one of the operation buttons:

   - Add: To add the two numbers.

   - Subtract: To subtract the second number from the first.

   - Multiply: To multiply the two numbers.

   - Divide: To divide the first number by the second.

4. The result will be displayed below the buttons in the "The Answer is:" section.

## Code Explanation

The core logic of the calculator is in the app.js file:

- AddNumber(): Handles the addition of two numbers.

- SubNumber(): Handles the subtraction of two numbers.

- MultiplyNumber(): Handles the multiplication of two numbers.

- DivNumber(): Handles the division of two numbers, with error handling for division by zero.

Each function retrieves the input values, performs the calculation, and updates the result in the DOM.
