  // ** Topics covered in this program: **
  // 1. Basic arithmetic operations in Dart (+, -, *, /)
  // 2. Declaring and using integer (`int`) variables to store whole numbers.
  // 3. Declaring and using double (`double`) variables to store decimal numbers.
  // 4. String interpolation (`$`) to embed variables within print statements.
