Do you think 1 1 2 is only used in mathematics?

It can only be used in the field of mathematics, in binary, 1+1=10, which does not conform to 1+1=2, it is just an equation that is mathematically considered to be defined, not absolute.

I think 1+1 2 is not only used in mathematics, but also in many other aspects of life.

It's just that a small part can't be used elsewhere, and in most cases, one plus one is still equal to two, which can be used in life, but in a few cases, it's not universal.

This rule is more applicable to mathematical situations, if it is in life, it is not necessarily, for example, two people together, it is not equal to two, many theorems are not immutable, mathematical theorems may not be applied everywhere.

It's not just used in mathematics, in everyday life, one person has one idea, then there are two ideas. It's actually a win-win situation.

This rule is universal throughout the universe, and there are many cases where 1+1 is not equal to 2, such as in binary. 1+1=10。Boolean algebra. 1+1=1。

This rule is not universal, but it can also be used in life, for example, in the cafeteria, if you tell the aunt to ask for two meals, it is not the same as adding an extra meal, and it can be clearly seen that the amount of two meals is more.

Except in mathematics, there is no place where one plus one equals two, such as in language. A hard work and a seriousness are equal to a good result.

One plus one equals two is only suitable for some aspects of life and mathematics, because different fields have different calculation methods.

This rule can be applied to all aspects of life, such as shopping, but it is not a universal method.

To be precise, it is a realistic number formula, and each number is followed by a special unit. But the results are all different.

That's right, that's what it literally means, and it can also be said that 1+1 = field.

In life, in most cases, one plus one is still equal to two. Different areas will have different rules.

A good wife and a good husband equals two people who love each other tightly.

One effort, plus one seriousness, is equal to two gains, sometimes even greater.

One food + one drink 0 The reason is very simple, you have destroyed ......!

1. If two numbers are the reciprocal of each other, the product of these two numbers is equal to 1

2. The power of zero of any number that is not equal to 0 is equal to 1

Any power is equal to 1

Any arithmetic root is equal to 1.

Yes for first-year students, not so much for high school students.

Mathematically, 1+1=2. This is a fact that all children in the nursery class know. But why 1+1=2?

Mathematical problems are everywhere in our lives, and these mathematical problems are diverse, but they are all worth thinking about, analyzing, and solving. I am now a junior high school student, and I have learned a lot of mathematics in the six years of primary school, but I have only now realized that so far, I don't even know how to get the problems that a child in the nursery class can do.

But now that I've found out about this problem, I'll definitely get to the bottom of it.

Why 1+1=2" seems like a simple question, but when I think about it deeply, I think it's so complicated, and I rack my brains to think about it, and my mind is blank. I turned to the internet for help, and I finally found the answer. There is an example on the Internet that says that the process of human understanding of the world is like the process of a child snowballing:

In the first step, the child should first hold a handful of snow with both hands, which is equivalent to the perceptual understanding of the world of human beings. In the second step, the child squeezes the snow in his hand tightly and becomes a small snowball, which is equivalent to human beings processing perceptual cognition and forming a concept. So there is 1.

In the third step, the child puts the snowball on the ground and finds that the snowball can stick to the snow on the ground, which is equivalent to the rational understanding of human beings. Snow can stick to snow, which is equivalent to 1+1=2. In the fourth step, the child rolls the snowball sticky with snow on the snow, and finds that the snowball sticks to the snow and gets bigger and bigger, which is equivalent to the advanced stage of human understanding of the world, and can enter a virtuous circle.

Equivalent to 2+1=, 2,3 can be arranged into the simplest sequence, but can be deduced to infinity. With 1 is just a concept, with 1+1=2 there is mathematics, and with 2+1=3 there is infinite change in mathematics.

After reading this example, I understood: because 1+1=2 is an axiom in mathematics, it does not need to be proved in mathematics; And because 1+1=2 is the basis of all mathematical theorems, it cannot be proved by mathematical methods, just like 1 cm is equal to 10 mm, assuming that 1+1 is not equal to 2, mathematics will be chaotic into a pot of porridge, and wherever mathematics is used, it will be chaotic into a pot of porridge, and society will be chaotic; So 1+1=2 doesn't have a why, and it doesn't need a why!

We can start by drawing a number line:

0"is the origin, so"0"This point has a special significance.

Now let's draw another number line, parallel to the original number line: --a

--b Note: When the number axis b"0"with the number line a"1"Relatively, the number axis b"1"Exactly the same as the number line a"2"Relatively.

That is, starting from 0, walking the distance between two units of length), to be able to reach 2

So 1+1=2
