1 1 Did you know that it s not two

1+1=2 is the equation for numerical calculations within the range of elementary mathematics.

It is known that there are three different categories of things in the world. One is the amount that fully satisfies additivity. For example, the total mass of the gas in the container is always equal to the sum of the masses of each gas molecule. For these quantities, 1+1=2 is perfectly true.

The second category is quantities that only partially satisfy additivity. For example, if the gases of two containers are combined, the temperature of the combined gas is the weighted average of the respective temperatures of the original gases (this is a generalized "addition"). But here's the catch

The amount of temperature does not fully satisfy additiveness because a single molecule has no temperature.

1+1 is 2 when you use mathematics to push, and if you use language to push 1+1 can also be equal to 1, because a drop of water plus a drop of water is still a drop of water, so you think that 1+1 is equal to a few is equal to a few!

1+1 should have = 2 But if you want to think about it crookedly, I'll give you two examples: greater than and less than and equal to two Is this kind of problem interesting It's boring Boss, in the math part 1+1 is equal.

One plus one equals two, and your house is not built.

You open a store, and someone buys two things for 1 yuan, and you say that he will give you two yuan, and if you want less than 2 yuan, he will be happy to think that you have not learned math well, and if you charge more than 2 yuan, he will fight with you.

If you don't want to admit that you didn't get kicked in the head by a donkey, that's right.

So how do you do this problem in math class? Doesn't it mean that both 2 are right?

There are also fields, but these are all for fun.

In the case of correct calculation, it is possible that two or two are equal to several in the case of wrong calculation

How much is 101 equal to? It depends on how you look at it.

In some number systems, such as octal, decimal, etc., 1+1 is equal to 2;

However, in binary, 1+1 is not equal to 2, but equal to "10";

It also depends on the unit, 1 + 1 = 2, 1 + 1 pair = 3, 1 pair + 1 pair = 4, 1 finger + 1 hand = 6 fingers, 1 day + 1 week = 8 days, 1 dozen + 1 = 13 ......

In logical operations, 1+1=1

Word game, one plus one = ten, = 11, = king, = abundance ......;

In life, 1 pile of soil + 1 pile of soil = 1 pile of soil, 1 pile of soil + 1 bucket of water = 1 pile of mud ......In society, if 2 people get married, 1+1=1 (1 family), and then have a child, it can be considered that 1+1 is equal to 3;

In terms of enterprise alliance, if it is a strong alliance, 1+1 is greater than 2; In the case of a weak combination, 1+1 is less than 2.

In the case of miscalculation, equal to any number is possible.

Wait. I hope the above is helpful to you.
