• + 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.
