some arithmetic operators work

main.dart

void main() {
  var result = 4 / 2;

  print(result);
  print(result.runtimeType);

  var result2 = 4.0 / 2.0;
  print(result2);
  print(result2.runtimeType);

  var result3 = 4.4 / 2.1;
  print(result3);
  print(result3.runtimeType);

  //modulo
  var remain = 7 % 3;
  print(remain);

  var pi = 3.14;

  print(pi == 3.14);
}
