Dart vs Kotlin: arithmetic operators

arithmetic.dart

void main() {
  var addition = 3 + 2; // 5
  var subtraction = 3 - 2; // 1
  var negation = -1; // -1
  var multiplication = 3 * 2; // 6
  var division = 3 / 2; // 1.5
  var integerDivision = 3 ~/ 2; // 1
  var modulo = 3 % 2; // 1
  modulo++; // 2
  modulo--; // 1
}
