Look at the unit, 1 0+ 1 0=2 0, 1+1 =2, 1 pair =3,1pair +65438+.
When the units are unified, people agree that: 1+ 1=2.
Maybe = two, = ten, =7, = 1 1, =4 1, = Wang, = Tian, = Lao, = Feng, = two. ...
In daily life, 1 drip+1 drip, 1 pile soil+1 pile soil, 1 pile soil+/bucket water = 1 pile mud.
In logical operation, 1+ 1= 1.
In binary, 1+ 1= 10.
Goldbach conjecture: Every even number not less than 6 is the sum of two odd prime numbers, that is, "1+ 1=2".
Two. Everyone's answer is different, and the answer will be strange; The following are my thoughts after answering some questions;
The first answer: 1+ 1=0.
You are a loose-minded person.
This kind of person is suitable for personnel work. He can use one person against another, and he is better at playing tricks. His career will climb quickly, and he can make friends with whoever he wants. There are very few real friends.
The second answer: 1+ 1= 1
You may be highly educated, but you don't think there will be such a simple problem. Your brain is more complicated.
The advantage of this kind of person is that they generally have the ability of management and coordination, cohesion, and can make two people twist into a rope. This kind of person is suitable for being a business leader.
The third answer: 1+ 1=2
(Most kindergarten children will blurt it out)
This kind of person has principles. No matter what you are, I follow the rules and do things strictly, and I am more suitable to be a scholar and scientist, such as "Shenzhou 7".
The fourth answer: 1+ 1=3
(You are a housewife),
Such a person will be a good husband and wife in the future, and will be a person who can live. It is happier to marry such a person.
The fifth answer:1+1> 2
You are extroverted and passionate.
Such a person can find the advantages of everything. Have brains. Can exert limited power to infinity, can be a politician, strategist, etc.
The sixth answer: 1+ 1= Wang.
(You are a non-professional type, or you may be in primary school.)
Such people do scientific research or technology development. Strong spatial thinking ability.
The seventh answer: 1+ 1= Feng.
You are calm and see the problem deeply.
Such people are more suitable to be inventors with rich imagination and strong logical thinking ability.
The eighth answer: 1+ 1= Tian.
You are considerate and like to put yourself in others' shoes.
This kind of person has rich imagination in space. More suitable for being a designer.
The ninth answer: the daughter of a colleague answered.
When my little girl was two years old (at that time, she only knew numbers within twenty), I held out an index finger in each hand. Leaned over and asked her, "Baby, what's one plus one?" She said loudly, "1 1". (I'm dizzy)
In Xu Chi's reportage, China people know the conjectures of Chen Jingrun and Goldbach.
Goldbach
Goldbach is a German middle school teacher and a famous mathematician. He was born in 1690, and was elected as an academician of Russian Academy of Sciences in 1725. 1742, Goldbach found in his teaching that every even number not less than 6 is the sum of two prime numbers (numbers that can only be divisible by 1 and itself). For example, 6=3+3, 12=5+7 and so on. 1742 on June 7, Goldbach wrote to the great mathematician Euler at that time, and put forward the following conjecture:
Goldbach's Conjecture
(a) Any even number ≥6 can be expressed as the sum of two prime numbers.
(b) Any odd number ≥9 can be expressed as the sum of no more than three prime numbers.
This is the famous Goldbach conjecture. In his reply to him on June 30th, Euler said that he thought this conjecture was correct, but he could not prove it. Describing such a simple problem, even a top mathematician like Euler can't prove it. This conjecture has attracted the attention of many mathematicians. Since Goldbach put forward this conjecture, many mathematicians have been trying to conquer it, but they have not succeeded. Of course, some people have done some specific verification work, such as: 6 = 3+3, 8 = 3+5, 10 = 5+5 = 3+7, 12 = 5+7,14 = 7+7 = 3+/kloc. Someone checked the even numbers within the 8th power of 33× 10 and greater than 6, and Goldbach conjecture (a) was established. But strict mathematical proof requires the efforts of mathematicians.
Since then, this famous mathematical problem has attracted the attention of thousands of mathematicians all over the world. 200 years have passed and no one has proved it. Goldbach conjecture has therefore become an unattainable "pearl" in the crown of mathematics. People's enthusiasm for Goldbach conjecture lasted for more than 200 years. Many mathematicians in the world try their best, but they still can't figure it out.

significant development
It was not until the 1920s that people began to approach it. 1920, the Norwegian mathematician Brown used an ancient screening method to prove and conclude that every even number greater than 6 can be expressed as (9+9). This method of narrowing the encirclement is very effective, so scientists gradually reduce the prime factor in each number from (99) until each number is a prime number, thus proving Goldbach's conjecture.
At present, the best result is proved by China mathematician Chen Jingrun in 1966, which is called Chen Theorem: "Any large enough even number is the sum of a prime number and a natural number, while the latter is only the product of two prime numbers." This result is often called a big even number and can be expressed as "1+2".
Before Chen Jingrun, the progress of even numbers can be expressed as the sum of the products of S prime numbers and T prime numbers (referred to as the "s+t" problem) as follows:
1920, Norway Brown proved "9+9".
1924, Latmach of Germany proved "7+7".
1932, Esterman proved "6+6".
1937, Lacey in Italy successively proved "5+7", "4+9", "3+ 15" and "2+366".
1938, Bukit Tiber of the Soviet Union proved "5+5".
1940, Bukit Tiber of the Soviet Union proved "4+4".
1948, Rini of the Hungarian Empire proved "1+C", where c is an infinite integer.
1956, Wang Yuan of China proved "3+4".
1957, Wang Yuan of China proved "3+3" and "2+3".
1962, Pan Chengdong of China and Barba of the Soviet Union proved "1+5", and Wang Yuan of China proved "1+4".
1965, Buchwitz Taber and vinogradov Jr. of the Soviet Union and Pemberley of Italy proved "1+3".
1966, China Chen Jingrun proved "1+2".
It took 46 years from Brown's proof of 1920 of "9+9" to Chen Jingrun's capture of 1966 of "+2". For more than 40 years since the birth of "Chen Theorem", people's further research on Goldbach's conjecture has been in vain.
