# Arithmetic Operations (Dart)

---

**Arithmetic Operations (Dart)**  
- `+` addition, `-` subtraction, `*` multiplication, `/` division (returns `double`), `~/` integer division (drops remainder), `%` modulo (remainder).  
- Example: `var x = 5 + 3; // 8`, `var y = 10 ~/ 4; // 2`, `var z = 10 % 4; // 2`.  
- Use parentheses to control order: `(a + b) * c`.  
- Convert between `int`/`double` with `toDouble()`/`toInt()` when mixing types.
