Does anyone know a few interesting answers

Fun "1+1".

May I ask 1+1=? I think everyone will say, "It's equal to 2!" "You'll be surprised, do you need to ask such a simple question? Even a three-year-old knows it! It's not just everyone who was surprised, I was surprised by a surprise that was bigger than the universe.

That day, in composition class, the composition teacher asked us, "Do you know that 1+1=??""2" we blurted out.

The teacher asked, "What else can it be equal to other than 2?" "One of the teacher's questions made us look at a loss, and we couldn't figure it out how we scratched our ears and cheeks.

This is Yan Huizi tentatively saying to the teacher: "Teacher, it is equal to Tian." "Why?

The teacher asked her. "Because if you separate the equal signs, put them above and below the plus signs, and then put the two 1s on both sides of the plus signs, isn't this a field character? "I'll write it on the table, yes!

I didn't think of that! It occurred to me that I thought: yes!

Aren't these words the same as Tian by Jia Shen? It's just that one is out of the head, one is out of the tail, and the other is out and out of the tail. So I said those three words in one breath.

Sure enough, the teacher gave me an approving look. We found the pattern, and before we knew it, we had a large ship of answers: 11, two, dan, old ......There are more than 20 of them!

I was about to think again, but the teacher had already told us that the time was up. Ah! If we continue to talk about it, maybe the blackboard with many answers will not be able to write it anymore!

Through this composition class, I realized that 1+1 has such a deep mystery! I'm going to dig out all the mysteries of it. I'm going to see what else he's hiding in his Duzuri.

Equal to 1, it can be seen that multiplication and division have a commutative law, 13 13 5 5 = 1

Equal to 120 Divide 240 into two parts, one is 120

3600。Using the multiplication exchange rate, first use 4 25 = 100, then 100 36 = 3600

To determine whether the following statements are correct, use " " or " " to indicate the judgment result.

1) The amplitude condition for maintaining the oscillation of the sine wave oscillation circuit is 1 fa. 2) As long as positive feedback is introduced into the circuit, a sine wave oscillation will inevitably occur. (3) If negative feedback is introduced into the circuit, it is impossible to produce a sine wave oscillation.

(4) The oscillation conditions of non-sine wave oscillation circuits are exactly the same as those of sine wave oscillation circuits. (5) When the integrated op amp works in the nonlinear region, the output voltage is either high or low. （

6) As long as the circuit satisfies 1 fa, it will inevitably produce a sine wave oscillation. ( Solution: (1) (2) 3) 4) 5) 6) The answer to this question is:

The equilibrium condition is a total gain of 1
