int b = 5;
int suma = a + b;
System.out.println("La suma es: " + suma);
int resta = a - b;
System.out.println("La resta es: " + resta);
int multiplicacion = a * b;
System.out.println("La multiplicacion es: " + multiplicacion);
int division = a / b;
System.out.println("La división es: " + division);
}
}
