I have experienced such a thing. In high school, I would get together with a very good classmate on weekends for the purpose of study. Parents also think that two people can improve each other together. However, as soon as we met, we talked about many things that had nothing to do with study. As a result, at the end of the day, we did very little homework. Later, Tsuzuka stopped us from being together, but the learning efficiency was improved. From this point of view, the two of us did not achieve the effect that 1+ 1 is equal to 2, but less than 2. But it is because of the weekend chat that this classmate and I became good friends who talked about everything, and the two separate ideas were promoted through communication. From this point of view, we have achieved the effect that 1+ 1 is greater than 2.
So I think whether 1+ 1 is greater than 2, we must first have a clear definition of greater than 2. Life and work are originally multiple goals, and it is impossible to have only one goal like mathematics. Goals are a guide to our work and life. Only when the direction is determined can we work well.
Secondly, to achieve the goal of 1+ 1 greater than 2, there must be synergy between two people, two organizations and two things. Simply put, the cooperation between them can reduce costs, use each other's resources to expand the market or reduce repetitive processes. In this way, no matter whether we study together or merge enterprises, there will be synergistic effect, which may reduce the cost, which is the premise for us to reach 1+ 1 greater than 2. From this, we can get enlightenment: cooperation must have the necessary premise, otherwise it is difficult to achieve the effect of 1+ 1 greater than 2.
Thirdly, in order to achieve the effect of 1+ 1 greater than 2, in addition to the possibilities mentioned above, specific operations should be controlled. For example, when I was a child, I did my homework with my classmates. It can be said that the goal is clear and the advantages of both sides complement each other. However, because the specific links are not well controlled, the effect of 1+ 1 less than 2 is obtained. The hardest thing to do in reality is this link. We should coordinate all aspects of our work, and our colleagues should unite, so as not to get too close to affect our work.
The idea of answering questions is: give an example when it is greater than 2 and less than 2.
