/*
 * Summary:
 *
 * This program demonstrates the following concepts learned in Day 1 of Dart:
 *
 *  - **Input/Output:** Uses `print` to display messages and `stdin.readLineSync` to get user input.
 *  - **Variables:** Declares and uses variables of type `int` (whole numbers) to store user input and calculation results.
 *  - **Data Types:** Uses the built-in `int` data type for whole numbers and implicitly converts user input (strings) to integers using `int.parse`.
 *  - **Basic Math Operations:** Performs addition, subtraction, multiplication, and division using arithmetic operators (+, -, *, /).
 *  - **Comments:** Includes comments to explain the code's functionality and improve readability.
 *
 * This code provides a basic example of user interaction, data manipulation, and calculations in Dart.
