Un microorganismo lo tenemos en le laboratorio a -7º . Queremos ver su reacción ante los distintos cambios de temperatura así que los subimos 5º , lo bajamos 3º, después lo subimos 25º y por último lo bajamos 7º. ¿Cuál es la temperatura final a la que tenemos el microorganismo?
-7 + 5 + 3 + 25 - 7 = 13
-7 + 5 - 3 + 25 - 7 = 13
7 + 5 - 3 + 25 - 7 = 27
-7 - 5 + 3 + 25 - 7 = 9
