So we can say that the change in entropy of the system plus the change in entropy of the surroundings is equal to the change in entropy of the universe. And that must always be greater than zero. It must always increase. It must always be a positive value. So we can still have a decrease in the entropy of the system. So this can still be a negative value as long as the increase in the entropy of the surroundings is greater than the decrease in the entropy of the system.
