A lot of beginners make this common mistake. It's a fun challenge that if statements are always checked even if previous statement is true. However, one might think of this as else if, and that the statement won't be executed.

void main() {
  int num = 10;
  if (num > 1)
    IO.println("It is greater than 1");
  if (num > 5)
    IO.println("It is greater than 5");
}
