Under what circumstances does 1+1 equal 3?

The answer to the brain teaser is when the answer is wrong.

When you ask others: "Under what circumstances does 1+1 = 3". Most people will definitely think that This is a "brain teaser" question, or a philosophical question of "adding a glass of water to a glass of water" or "adding a pile of sand to a pile". But will "3" appear in this way? More People think of the answer "a man and a woman give birth to a child"! In fact, things are not that complicated at all. This is just an elementary school mathematics problem! In elementary school mathematics, in the case of rounding from 4 to 5 , there is nearly 1/3 but less than 1/3 probability that 1+1=3, from 1.1 to 1.4 (I am only talking about one digit after the decimal point now), when rounding from 4 to 5, it is still " 1", for example, 1.2+1.3 is =2.5. If it is rounded from 4 to 5, it must be "3". By analogy, from 1.1 to 1.4, how many combinations are there? It can be 1.1+1.4, the same 1.4+1.4 is also true, and 1.3+1.4 is also true. As long as the result is greater than or equal to 2.5, it is true. Excluding the two numbers 1 and 1.5, the probability is less than 1/3. Because the real "1 +1" can only =2; but "1.5+1.5" is really =3! Under the above conditions, "1+1.5" cannot be established, and "1.5" becomes true if 4 is rounded to 5. "2". However, what we are talking about here is the problem of "1+1=3"! When it is extended to all aspects of society and other aspects, there are even more problems. "1+1=3" is mathematically established, but in In real society, this phenomenon is not uncommon. In fact, "1+1=3", is this "3" really "3"? At the same time, since when 4 is rounded to 5, "1+1=3" has The probability of 1/3 is established. Then there is also a probability of 1/3 that it is "1+1=1"! Think about it again: 0.5 or above, is it "1" when rounding from 4 to 5? So , since we accept that "1+1=3" is established, we must also admit that "1+1=1" is also established! However, the vast majority of people in our shameless society regard themselves as "1+1=3" He is elated when he has vested interests. But when he sometimes falls into "1+1=1", he shouts "unfair"! This is a Chinese-style "predatory method", and the "being" in society... This is the principle. Similarly, there are some shameless people who deliberately forget how they got their "3" and take it for granted that 3+3=6, but their "3" is really 3 ?, when he was in "1+1=3", he said, "How can there be so much 'fair' in this world?" However, when he used this "3" to make "3+3", The result can only be "=5". Then he jumped out and said "unfair"! We Guangzhou people usually say "eat salted fish to satisfy your thirst" and northerners say "willing to accept defeat". This is a kind of A correct outlook on life. But can the current Chinese people do it? They require others to be "1+1=2" and think that they should be "1+1=3". For "1+" that happens to others 1=1", they said, "How can there be so much fairness in this world?" Some officials even publicly said, "If there was so much fairness in the world, how would it be?! (Typical Chinese characteristics)" But when they When you are in the situation of "1+1=1", you shout "unfair"! Don't forget, you are in the first grade of junior high school, and others are in the fifteenth grade. But Chinese people always think about "losing and winning"! Someone asked me : What does this "1+1=3" have to do with photography? Why do you always ask this question during the exam for apprenticeship (no charge)? This point is very commonly used in landscape photography, and it is truly Many of those immortal works used this technique, which is the technique of "moving the focus forward to 'expand' the range of depth of field." However, each author differs according to his or her own level of cognition and understanding. It’s just a different expression. At the same time, if the author expresses it so straightforwardly, it will only attract the disapproval of the vast majority of people. When I was studying photography art at Guangzhou Engineering Vocational and Technical College, Teacher Tan Zhengrong was teaching us This photography technique was taught in the "Landscape Photography" class, but it was considered "nonsense" by everyone (even if it was not said publicly, it was thought privately). Because this creative technique itself uses human vision. Wrong. The essence of artistic creation is a kind of visual artistic communication. And I always have to ask this question, not whether the person knows or understands this photography technique or principle, but whether his thinking can jump out. Ordinary people have inherent conceptual circles. What’s more important is that they understand: Don’t make something that is originally simple become very complicated!
