1+ 1=? To test your mind or make a joke.

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)

The quantity is far beyond my expectation ~

1+ 1= 1 indicates that a father and a mother gave birth to a baby.

1+ 1 = 3 A father and a mother became a family of three after giving birth to a baby.

1+ 1 = 4 A father and a mother gave birth to twins and became a family of four.

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 teaching that every even number not less than 6 is the sum of two prime numbers (numbers that can only be divisible by themselves). 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:

(a) Any > even number =6 can be expressed as the sum of two odd prime numbers.

(b) Any odd number > 9 can be expressed as the sum of three odd 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 33× 108 and above 6 one by one, 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.
