My Girlfriend is More Than Beautiful

Jingle Bell.

The bell rang for the end of get out of class, and Li Ziqian got up from his seat after completing the last steps in his seat.

Eating is not active, thinking has problems.

In just a minute or so, most of the classmates in the classroom had already dispersed.

"How to say?"

Li Ziqian got up and stretched, looking at Mo Nanbei who was also sorting out the papers stacked on the table, and asked her.

"Go to the supermarket to buy stutter, then come back and talk about it."

"OK."

Unfortunately, he thought so too.

In the case of losing the first opportunity, if you go to the cafeteria now to line up, then when you come back after eating, it will take thirty minutes to start.

Kind of a waste of time.

Anyway, he is not very hungry now. Go to the supermarket to buy some bread, and then drop by to order a cup of milk tea. Isn't this much more comfortable than going to the cafeteria to squeeze people?

As for how to go out of school to buy milk tea?

It depends on the relationship with the uncle of the guard room, as well as 'acting'.

Fifteen minutes later, Li Ziqian returned to the classroom, and Mo Nanbei also returned shortly after.

She was holding a white plastic bag from the school supermarket in one hand and a cup of milk tea in the other.

Walking back to her seat, Mo Nanbei threw the things in her hand onto the table, then took out the paper she had written in the previous self-study class from the hole in the table, and said to Li Ziqian,

"I see that you have been writing in your self-study class, so you also wrote your part of volume three by the way."

"Ah this..."

Too many elements.

This is the only thought in Mo Nanbei's mind since he entered the door to the present.

Leaving aside the exact same dinner setup, he didn't know how to say it just because it was also written in Volume Three.

And Mo Nanbei looked at the paper and the delicate expression in Li Ziqian's hand, she probably understood what happened.

Leaning back slightly tactically, Mo Nanbei blinked in confusion and asked Li Ziqian,

"Then... Since that's the case, let's get the answer right?"

"also."

"Then let's get the answer right."

"it is good."

With that said, Li Ziqian picked up the third volume and read out the answer to his multiple-choice question.

"Multiple Choice, ACDAC"

"ACDDC", Mo Nanbei frowned slightly and said her answer with a little doubt.

"Question four?"

Li Ziqian questioned the inconsistency of the two answers to this question, so he continued,

"Obviously the choice is A."

"Huh? Isn't that an obvious choice for D?"

In the face of Li Ziqian's tone of "you specified that there is a problem", Mo Nanbei gave the same response.

"No, this question is very obvious, you read the question and take a good look at what you are writing!"

"You can do this problem if you have a hand. How can someone be wrong? It's obviously D. What do you think?"

"I wrote the steps, this question."

"It's not a coincidence, I wrote it too."

"Come on, show it to me."

"I think so too. This question is not right. What are you studying? Find a job in an electronics factory?"

They didn't stop for a moment while they were rummaging through the steps to do the question.

"I found it.

What if you get this wrong? ”, slammed the paper with the steps written on it on the table, Li Ziqian asked Mo Nanbei.

"Smile, can I get this wrong?"

"bet?"

"Bet what?"

While asking the question, Mo Nanbei leaned back on the back of the chair, raised his right leg over his left, raised his eyebrows and raised his chin slightly to ask Li Ziqian.

Obviously, she is also very interested in the 'bet' thing.

what to bet...

Glancing at the things on the table, Li Ziqian blurted out and made his debut,

"Ten cups of milk tea."

"Clam?"

"What, cowardly?"

"Coward your mother!"

"Okay! Then bet!"

"Then bet!"

Li Ziqian felt a little incredible, but also felt that it was reasonable.

I always feel that if it is done with my own hxd, it is very common, but now the object of the gang line is actually a female tablemate who is only a companion who only communicates for a day...

Subtle mood?

Li Ziqian did not continue to think about detailed and complicated matters, and now his focus is all on the fourth multiple-choice question in volume three.

The topic is this:

Pyramid is one of the architectural wonders of the ancient world. Its shape can be regarded as a regular quadrangular pyramid. The area of ​​the square with the height of the quadrangular pyramid as the side length is equal to the area of ​​the triangle on one side of the quadrangular pyramid. What is the ratio of the side lengths of the square on the ground?

The four options, AC are, respectively, the square root of five plus or minus one; BD are, respectively, the square root of five plus or minus one.

The result of Li Ziqian's calculation is A, that is, the square root of five minus one to four.

Mo Nanbei felt that D should be chosen for this question, that is, the square root of half plus one.

"How did you calculate this question?"

Li Ziqian, who felt that he would definitely not have a problem, asked Mo Nanbei preemptively.

"It's very simple. Let the base of the side triangle be a and the height be h."

Mo Nanbei put the thumbnail that he drew on the scratch paper in front of Li Ziqian, circled his steps, and continued to say to Li Ziqian,

"In this case, the height of the side triangle, half of the side length of the base square, and the height of the regular quadrangular pyramid form a triangle.

In this way, the expression for the height of the regular quadrangular pyramid is obtained, and it is enough to solve it later. "

'The high expressions are the same...'

Listening to Mo Nanbei's remarks, Li Ziqian turned his head and glanced at the steps on his scratch paper.

His solution to this problem is not the same as Mo Nanbei.

He first deduced the expression of the two isosceles side lengths of the side triangle, and then obtained the expression of the height of the regular quadrangular pyramid based on the side length and diagonal of the base square.

But... the expressions of high are the same, so in the end, it is the problem of the solution?

Theoretically speaking, this step has already been introduced, so it makes no sense that the following questions cannot be solved, right? Doesn't make sense, the answer is different, right?

If you analyze the wave, then the two of them have different answers and the reason is the calculation problem?

Thinking about it, he picked up Mo Nanbei's scratch paper, carefully looked at the steps, and began to count on the white paper beside him.

The equation is 4x2-2x-1=0. After solving it, x=1±root number five, which is more than 4…

4!

Mo Nanbei's denominator says 2!

"Hey, tell me!"

? ? ?

Again... at the same time?

"You counted wrong."

"what??"

It was two consecutive unanimous voices.

When Li Ziqian discovered Mo Nanbei's mistake, the other party also seemed to have discovered his problem.

"No, I found out that you counted the wrong number." Li Ziqian said.

"Well, I also found that you made a wrong calculation." Mo Nanbei said to Li Ziqian after being stunned for a while.

"…"

Li Ziqian looked down at the answer he had come up with on the paper.

The square root of five plus one to four.

He was lost in thought.
