See how you understand;
1. If you put something under your arm, it will disappear.
2. 1+ 1=02. Two people get married and form a new family. 1+ 1= 1
3. Children's computational mathematics. 1+ 1=2
When two people get married, a crystallization of love becomes a family of three. 1+ 1=3
5. 1+ 1 equals no three no four.
6. 1+ 1 equals 1 1.
7. 1+ 1 equals the king.
8. 1+ 1 equals Tian.
9. Goldbach conjecture; 1+ 1 equals the jewel in the crown of mathematics.
10, binary. 1+ 1= 10,
1 1, Boolean algebra. 1+ 1= 1,
12, a cat and a mouse equals a good meal.
This is an unsolved problem. Mathematically, it is equal to two. There are less than two chemists. Life is greater than two!
This seems to be a simple question. If you really want to know why even children laugh at you, the great mathematician Chen Jingyun only studies why 1+2 equals 3. Why 1+ 1 equals 2 is not a simple question. 1+2=3: Mathematics is called the crown of mathematics. 1+ 1=2: Mathematics is called the jewel in the crown of mathematics. We will develop it.
That is, in the field of mathematics, Goldbach put forward the conjecture of even number = prime number+prime number, which is simply expressed as 1+ 1=2.
Then now the great mathematician Chen Jingyun pushes this conjecture to even number = prime number+prime number * prime number, which is a little worse than Goldbach's conjecture. So, what is 1+ 1? I don't know ...
