Why did A treat B 10 this way

A may like B, but B may not, it depends on B's tone of letting A sweep the floor at that time, if it is a joke, then B is better than an average friend of A, which can be said to be beyond the ordinary. However, if the tone is not very good, then forget this person, don't even do it with ordinary friends, and what is "A and B are college classmates and have known each other for 3 years"! I advise A not to take his feelings lightly on a person who will not give you anything in return.

I hope the answer is good! In fact, only you know the answer! Isn't it!

Haha, A likes B

B is hard to say

It's hard to say ...... about feelings

If a girl sweeps the house and sleeps in a boy's house, it ......If the boy agrees, ......

It can be seen that the relationship between the two people is not ordinary......

It's not a couple, it's also a relationship ...... sworn friends

Maybe boys like girls too, but they just don't know how to express ......Or maybe two people are just just good ......

Honestly......I don't really believe in the ...... of a purely friendly relationship between men and women

It's directly that A likes B, so why bother to go around such a big circle? It's all so direct, how can that b refuse directly, you can't see his attitude if you're too active.

Girls are likely to like boys.

The boy thanked the girl for helping him clean up, and he thanked her more.

A should like B

B is hard to say about A!! @

Probably like it too!! Because he didn't call A

It could also be a friendship!!

A should like B, but B may not, it's just that it's hard to refute the other side.

A likes B...However, B has little affection for A.

But love has to be said to have a further development.

I hope that the landlord will get the love that truly belongs to him.

A likes B...It's too obvious. B doesn't like A. It's also obvious.

A is a bit self-inflicted

I don't like it, I think it's too complicated.

It's not that it can't be deduced, but it can't be concluded that the existing a is not b from the condition that there is a is b, because"Yes"The logical connotation is: at least one, i.e., greater than or equal to 1, containing three possibilities:

1.There is only one.

2.There are parts.

3.There are all.

Therefore, some A is B, and it cannot be concluded that some A is not B.

Mathematics [English: mathematics, from the ancient Greek máthēma);Often abbreviated as math or maths], it is a discipline that studies concepts such as quantity, structure, change, space, and information.

History: Mathematical limbs are a universal means for humans to strictly describe the abstract structure and pattern of things, which can be applied to any problem in the real world, and all mathematical objects are inherently artificially defined. In this sense, mathematics belongs to the formal sciences.

And not natural science. Different mathematicians and philosophers have a range of opinions on the exact scope and definition of mathematics.

in the history of mankind.

Mathematics plays an irreplaceable role in development and social life, and it is also an indispensable basic tool for learning and researching modern science and technology.

e.g. a= 1,2 beams.

b＝﹛2,3｝

a b First car transport {1,2,3}

Then (a+b)-b={1} sail rolls≠a

The general solution needs to be represented by the basic solution system, and the basic solution system must be linear independent, this question says that the coefficient matrix is of the third order, and the rank is 2, indicating that there is an irrelevant solution in the basic solution system, then it is necessary to ensure that this vector is a non-zero solution, this question says that a, b are both solutions, but it does not say whether they are non-zero, a, b is wrong, and they do not use, that can only ensure that the difference is non-zero, and the sum is not necessarily, so c is not right, choose d

I once thought of a teacher in my high school, when he commented on the topic, he said: "Look at this question, it is obvious that this question is to choose D, A is impossible, B is obviously wrong, C is absolutely wrong, how can anyone choose C." So the correct answer is to choose D, okay for the next question".

Isn't that another d's?

Draw a picture and it will be clear.

The above relationship is also satisfied, but not an increment.

In logical deductive reasoning, "as long as A is B" is a sufficiently conditional hypothetical proposition, and "Only A is B" is a necessary conditional hypothetical proposition, and you can distinguish between the two completely formally, without caring about what A and B are.

As long as A is B, it means a sufficient conditional hypothesis, that is, there must be B if there is A, there must be no A without B, and other conditions are not necessarily.

Only A is B, which is a necessary condition hypothetical proposition, that is, there must be no B without A, and there must be A if there is B.

For example, whenever it rains, cancel the gathering. In other words, if it rains, the rally will be cancelled.

In other words, if the rally is not canceled, it must mean that it is not raining. However, if it is known that it is not raining, it does not mean that the rally must have taken place, and similarly, if the rally is known to be cancelled, it does not mean that it is raining. Because there may be other reasons for canceling the rally.

Only when it rained did the rally be cancelled. That is, if it doesn't rain, the rally won't be canceled. The rally was canceled, and Ran Tsai said it was raining. However, if there is known to be rain, it does not necessarily mean that the rally has not been cancelled, and similarly, the fact that the rally has not been cancelled does not mean that it must not have rained.

You can also verify this with some examples yourself. In short, logical deductive reasoning focuses on the form of reasoning, judging what kind of proposition a proposition belongs to from the buried form of the connecting word, and then reasoning formally according to the corresponding reasoning rules, without having to consider the specific content of the proposition too much.

Hope it works for you.
