Professor Mike is a tolerant teacher. Although he sees the discord between the two, he does not intend to interfere.
The noise among children is childish and ridiculous in the eyes of the elderly.
He actually had no hope that Luo Wei could answer this question. After all, this question was indeed difficult for them, and it was only normal that they couldn't answer it.
"Luo Wei, are you willing to answer this question?" Professor Mike was already prepared to be rejected.
Luo Wei had already calculated the answer in her head, and stood up when he heard him ask: "The answer is the square root of three, which is approximately equal to 1.7 inches."
"If you don't want to, don't do it...wait a minute," Professor Mike's eyes were glaring, "Tell me again, what's your answer?"
Wei Na almost laughed out loud, hahaha, what is the prescription of three, this is also called the answer?
Professor Mike was definitely going to be angry because he didn't know arithmetic and still answered randomly. She looked at Luo Wei with pity.
Luo Wei's attention was not on Vina at all. She answered Mike seriously: "My answer is the square root of three, which is approximately equal to 1.7 inches."
To be honest, she didn't know what to do because she didn't know how far mathematics in this world had developed.
However, there were radical numbers in Europe in the Middle Ages, but the pronunciation was different in different regions. The most common reading was "the square root of a certain number", and she used this reading to replace the radical three.
Professor Mike's eyes became brighter and brighter: "Can you calculate square roots and trigonometric numbers?"
It seemed that her answer was correct. Luo Wei breathed a sigh of relief and said humbly: "I'm lucky enough to have learned a little bit and I haven't forgotten it yet."
"My child, you are so humble." Professor Mike praised, "I have taught many students, but most of them can't understand and can only draw pictures rigidly."
Luo Wei couldn't answer this, so she kept smiling.
The more Professor Mike looked at her, the more satisfied he became: "Good boy, sit down."
He looked at the others again: "Luo Wei's answer is correct, has anyone figured it out?"
Wei Na looked incredulous. Why did Luo Wei know the answer? She didn't even write it.
She refused to give up: "Professor, don't you ask Luo Wei how she calculated it? I didn't even see her using a sand table to calculate it."
Hearing what she said, the students in the class craned their necks to look at Luo Wei's sand table.
"It's really not true. Did Luo Wei do mental arithmetic? That's amazing!"
"Luo Wei must be a genius!"
"As expected of a young lady from a noble family..."
Vina's teeth were about to break. She wanted them to question her, not praise her!
Professor Mike glanced at Vina disappointedly and called out to Luo Wei: "Good boy, can you tell us your ideas for solving the problem?"
Luo Wei nodded, with a calm expression: "First calculate the distance from the center point of the hexagram to the six corners, and then calculate the vertical distance from the intersection of the diagonals of the square to the sides, which is the radius of the largest circle in the square."
"Then calculate the ratio between the two, and use the ratio to get the line length of the reduced hexagram."
There was a sound of "rustling" in the classroom, and the students hurriedly scratched back and forth on the sand table.
So that’s how it is, that’s how it’s supposed to be calculated!
Half of the people looked enlightened, and the other half pulled their hair in pain.
But in the end, many people looked confused.
The method is known, but how to calculate the distance from the center point of the hexagram to the six corners?
Seeing this, Professor Mike smiled slyly: "It won't count, right? It won't count."
"I didn't want you to calculate this question in the first place. I just wanted to use it to elicit the arithmetic knowledge I will talk about below."
"Trigonometric numbers, and square roots."
students:! ! !
They looked at Mike sadly: "Professor, you are too bad!"
Professor Mike laughed loudly: "Professor, I am a humorous person. Sit down quickly, children, I am going to continue the lecture."
The students sat upright, picked up small wooden sticks and looked at the board seriously.
Wei Na also sat down gloomily.
She didn't understand, Luo Wei was obviously a commoner, why did he know so many things?
Is she really a noble?
After class, Luo Wei walked out of the classroom, followed by a little tail.
After walking for a while, she turned around helplessly: "Vina, what do you want to do?"
Wei Na looked at her with complicated eyes: "Are you really a noble? Which country are you from, and what is the title of your family?"
Luo Wei looked cold: "Vina, it's rude of you to ask this."
"Shut up!" A trace of resentment appeared on Wei Na's face, obviously remembering what she had said to her yesterday.
Luo Wei stopped paying attention to her, turned and walked towards the cafeteria.
The midday sun was a bit dazzling, and a group of young boys and girls walked through the avenue talking and laughing, heading to the college restaurant together.
"Crash-"
The copper coins were scattered on the ground, and some of them rolled into the grass along the sloping road.
"Ah!" The girl bent down to pick up the copper coins in a panic, sweating profusely in the flow of people, "I'm sorry, please let me go, my copper coin fell... Please lift your feet, my copper coin was You stepped on it...Thank you, I'm extremely sorry..."
A copper coin rolled to Luo Wei's feet, but she blocked it with her feet.
She looked at the girl, picked up the copper coins and stepped forward: "Your——"
"Ah, I'm sorry, did I block your way?" Seeing a gorgeous skirt, the girl hurriedly stood up and gave way, "I'm sorry, I didn't mean to do it."
Luo Wei pursed her lips and handed out the copper coins: "I just want to say, I'll give you your copper coins."
The girl suddenly raised her head and looked at her eyes widening, as if she was shocked.
After seeing the girl's face clearly, Luo Wei was also stunned for a moment.
In the memory of the original owner for the next seven days, this was the only person who found a way to feed her water when she was hanging on the city wall in public.
And those civilians, obviously civilians, were also clamoring to kill her.
Luo Wei's eyes darkened, she came back to her senses, and stretched her hand forward: "Don't you want it?"
The girl quickly wiped her hands on her clothes and took the copper coins with both hands respectfully: "Thank you, thank you very much!"
"You're welcome," Luo Wei knelt down, "I'll pick it up for you."
"No, it will stain your skirt," the girl hurriedly stopped, "I can do it myself."
"It doesn't matter, it's just dirty when it's dirty." Luo Wei picked up the copper coins in the grass. Out of the corner of his eye, he noticed that she had been looking at him, and turned around and asked, "What's wrong?"
The girl shook her head in embarrassment: "No, it's nothing, it's just the first time I've met a noble and kind lady like you."
Luo Wei paused, picked up the copper coin and handed it to her: "What's your name?"
The girl straightened her back nervously: "My name is Winnie, Winnie Charlie."
"My name is Luo Wei," Luo Wei stretched out her hand, "Winnie, can we be friends?"
"Of course!" Winnie held her hand and helped her up, saying with bright eyes, "As long as you don't dislike it!"
Luo Wei...
She meant to hold hands, not to help her up.
Well, it seems that the handshake ceremony is not very popular among civilians.
"You count, have you picked them all up?"
Winnie counted it once, and finally a smile appeared on her face. She thanked Luo Wei gratefully: "Fortunately, you helped me, otherwise I wouldn't have been able to raise the money to rent the horse."
"Rent a horse?"
Winnie nodded: "I am an intermediate magic apprentice. There is an entrance exam the day after tomorrow, and I have to take the equestrian test. I can't afford a horse, so I have to rent it."
"For equestrian classes, doesn't the college provide free horses to students?" Luo Wei thought to herself, because she didn't have the money to buy a horse.
"Provided, but those horses are very old," Winnie explained. "Aristocratic students all use their own horses, which run very fast. If my grades are too poor, I will lose the qualification for free tuition."
Can tuition be waived?
The poor Luo Wei was moved. Her tuition fees for the next semester have not yet been paid.
"Is it difficult to obtain tuition-free qualifications?" she asked casually.
