Another world, I have an elf magician

“The school needs to increase the floor space as much as possible, and other shapes except squares don’t seem to occupy much space.

If we build directly around the edge, we don’t know exactly how much area there is, materials are not ready, and the construction team can’t start.

So, I think Box's suggestion is very good, but even so, it will take a long time. "

Teacher Sasha was more in favor of Box's suggestion. Some of the other students nodded in agreement, while some were still thinking with their heads down.

I looked at the drawing in my hand, resting my chin in a daze.

Even with mental arithmetic, I can calculate the area of ​​the circle on the drawing, which should be 96162.5 square meters.

This is not a problem at all for me. After all, it is knowledge from elementary school in my previous life.

But in this different world, such a simple elementary school arithmetic problem has actually become a world-class problem?

If I had known about this in my previous life, I would have been dumbfounded with surprise. I would have thought that people in this world are all mentally retarded, right?

But after all, I have lived in this world for 15 years, and I definitely would not have such thoughts.

After all, if they think about it from their perspective, if they knew that humans in a certain world didn't even know the most basic magic, wouldn't they also despise and ridicule them?

Just like city people can't tell the difference between rice and wheat when they go to the countryside, while rural people can't tell the difference between traffic lights when they go to the city, and they look down on each other.

"Randy, what do you think?"

Sasha asked me a question. I came to my senses and said casually: "The area of ​​this circle is about 140 acres."

After I finished speaking, I noticed that the whole classroom immediately became quiet, you could hear a needle drop, and everyone focused on me.

"Randy, are you lying? 140 acres of land, do you know how big it is?"

"That's right, you must be talking nonsense. Is it possible that you can calculate the area of ​​a circle?"

"If he can figure it out, it will cause a sensation in the world. We will all have to call him Dr. Randy from now on, hahaha!"

The students around me burst into laughter. Box was the first to question me, and he seemed to be deeply disbelieving in me.

There hasn't been a big change in my heart. I just feel that these people are a little ignorant, but they are normal human reactions and can be tolerated and understood.

After all, for a seemingly normal math problem, it may have taken predecessors decades, or even hundreds of years, to figure out the correct result.

I just stand on the shoulders of giants and look down on them. My own level is not even an ant in mathematics, so I am not qualified to ridicule them.

"Randy, why did you determine that the area is 140 acres? Is it possible that you know the correct answer?

You know, the circle is the most difficult figure in the world to calculate the area, so when we encounter this problem, we can only use other figures to solve it, but in the end there will still be deviations. "

Teacher Sasha asked.

I coughed lightly and said seriously: "Of course there will be deviations. If the outline of the circle is taken apart and then formed into a square for calculation, wouldn't it be a waste of time and effort?

Moreover, I just said that this circle covers an area of ​​about 140 acres, and the real area is 96162.5 square meters. "

Looking at everyone again, I found a trace of doubt in their eyes, even Teacher Sasha.

So, I stood up directly, walked to the podium, picked up the chalk and started explaining on the blackboard.

After all, I had completed nine years of compulsory education in my previous life. If I couldn't understand elementary school arithmetic problems, then I would have learned nothing.

Ten minutes later, I finished explaining, left the formulas and notes on the blackboard, and returned to my seat under the stunned eyes of everyone.

I gave them a rough explanation of the meaning of π, and then the formula for the area of ​​a circle.

Noticing Teacher Sasha's disbelieving look, I touched my nose and thought whether these people could understand or not, that was their business.

After class, I saw Teacher Sasha copying the formulas and explanation diagrams on the blackboard into her notebook, saying that she would take them to the principal for further study.

I didn't pay much attention to it, but Box came over to tease me a few times after class and insisted that his method was right.

I remember what he proposed was to print the outline of the circle on a piece of paper, then split it into four equal-length sides, combine them into a square, and then calculate the area of ​​the square.

If it were in his previous life, he would definitely be regarded as SB.

The whole morning ended like this.

During lunch break, I lay on the bed in the dormitory, but actually my soul entered the spiritual space of the Lord of the Rings to practice magic.

Because I was almost killed by a dark magician before, I am obsessed with becoming stronger.

Time was ignored by me, and I didn’t know how long I had been in this spiritual space that was different from the outside world.

Maybe several years, maybe not?

In short, I have only one goal, and that is to become stronger.

There is good news and bad news on this day.

That is, the school's planning map has been calculated and has been highly recognized by the political company.

The reason is that my area formula has been unanimously praised, and Principal Bick said at the commendation meeting that the formula I proposed has been quickly spread to the imperial capital.

There were some people there who were interested in mathematics who wanted to see me, but the distance was too far, so I could only visit them later when I had the chance.

Fortunately, I just did it unintentionally, but I got the opportunity to enter the Imperial Capital for free in the future. As long as I mentioned my name, someone would greet me immediately after entering the Imperial Capital.

This is considered a benefit, I really didn’t expect it.

I remember that at today's commendation meeting, I clearly saw the shame on Box's face. He seemed to feel ashamed.

I didn't care too much about his opinion, so I didn't think too much about it.

In this world, except for your loved ones, no one will care too much about what you are thinking, and some of them are just for profit.

Therefore, face belongs to you, not others. It is actually wrong to care too much about what others think of you. We live for ourselves, not for others.

After the commendation meeting, I got some bad news.

That is, Lilith is missing.

This incident spread quickly in the school. The reason was that Teacher Sasha secretly helped Lilith and asked her to join the Adventurer's Guild to take on tasks and subsidize her living expenses.

Originally, Lilith's missions were always E-level, but I heard that a personal sponsor found her and entrusted her with a D-level mission. I don't know what it was specifically, but Lilith disappeared after accepting the mission.

Some students are rumoring whether she was sold to the slave market to become a slave, or tricked into going to Flower Street to do that kind of service.

There are quite a few people who spread rumors, and I only found out the specific situation after asking Director Wayne for confirmation.

Teacher Sasha was put on hold because of this, and the specific disposition is still to be determined. She may be responsible for the blame later.

After all, a human life is at stake, not to mention that Lilith is a noble.
