[suppose there are a number of mages and a single headed four legged wizard in the same venue, counting from the top, there are 35 heads, counting from the bottom, there are 94 feet. How many magic masters and magic guides are there in the venue
A simple problem of chicken and rabbit in the same cage.
But it's not so easy for freshmen who have just been exposed to the equation for an hour.
Professor lily has been in the classroom for a long time. She thinks that if anyone comes to solve the problem at this time, there may be some embarrassing situation that she doesn't want to see. Instead of calling the roll randomly, she chooses Emma Metis in the front row.
As Emma got up on stage, all the students in the classroom were quietly relieved - not by themselves!
Emma carefully recalled Professor Lily's previous example. Although she didn't quite understand it, the format of this problem is almost the same as that of the example. It's not difficult to imitate the example.
She quickly wrote out the answer.
"Right! Emma mertiska, five points
Professor lily is obviously a little excited and feels that she has a talent for teaching.
Isn't it just once that someone has learned it?
After the problem as long as use exercises to consolidate it! Remember the website novelhall.com
Fortunately, she worked overtime last night to make a test paper, which is not used?
Perfect!
……
After that, instead of looking for someone to answer the question, she explained Emma's answer to the question and began to distribute the test paper.
The difficulty of the test paper is not too high. It can be solved by self-study according to the textbook.
What can be photographed is that there is no textbook!
……
"Ding Ling Ling!"
Arithmetic class is coming to an end in the whirling of examination papers.
Professor Lily gave her teaching a score of nine and left the classroom with satisfaction.
Only numb faces were left.
……
"Ah
I don't know who was the first to shout, and the classroom was filled with grief.
Susan and Lucy frowned and looked at one side of the paper. Then they looked at Emma as if they wanted to make friends with Emma. It was the wisest choice they made last year!
Diana and rose in the back row are also holding a dense notebook, looking at dak eagerly.
"The library in the evening," he said
Diana: Yes
Rose: Hoo
The pressure to be around top students is still relatively high.
At the beginning of school, neither of them cared so much about their grades.
Now it has subconsciously care.
……
On the other side, Witt and Robert face to face, eye to eye, all gray.
Both of them have been very hard at this course, and now they are even more black eyed.
Robert is a rare one recently. He almost fell asleep.
After a while, Witt whispered, "why don't I ask sister Betty?"
All he could think of was Betty and Scott.
But Scott
Fortunately, I got acquainted with Betty on the last secret road exploration!
As for "Dake" and "gap", he didn't even think about it.
……
Until the beginning of the course, the students are still worried about it.
Professor kazel asked a student curiously, "what happened? Why are they all suffering? "
The student complained: "Professor, the arithmetic class is so difficult. We need help!"
"So it is." Professor kazel waved his wand to make him sit down and said with a smile, "don't worry, if you can't pass the final exam, you can have a tutorial next semester."
The classroom suddenly became deserted.
Professor kazel didn't care about this. Instead, he said, "close the textbook. Today we are going to teach a special kind of magic card making - kill card!"
"Must kill card?"
The students couldn't help looking up at the platform.
What Professor kazel said obviously aroused the interest of most people.
There are many categories of magic cards, including kill cards and magic cards.
But compared with the more popular magic card, Bisha technology card can only be regarded as a minority category.
No matter in actual combat or duel, few people will use the kill card.
Because the must kill card has no advantage in effect and refining, it has more restrictions than the magic card.
Most of the magic cards only need the magic power provided by the magic tutor to use, but the kill card needs to summon the corresponding magic guide spirit to cooperate with the magic guide spirit to use!
Moreover, according to the degree of tacit understanding between the mage and the wizard, it is easy to make mistakes in cooperation... That is really giving in vain.
However, in the early stage when the mage didn't learn the language of magic director and couldn't refine the magic card, he didn't need to learn the language of magic director to have the chance to refine the kill skill card successfully. On the contrary, he had unique advantages.
But it's not part of the textbook, it's professor kazel's personal teaching.
In a few minutes.
Professor kazel gave a brief introduction to Bisha technology card, and then began to explain the application and refining methods of Bisha technology card in detail.
Of course, this class is only to explain the theoretical knowledge, practice teaching can only be put on the next week.
First year students have to prepare the materials for the experiment before the next lesson of magic guide theory.
As for the credits required for self purchased materials
The poor have the poor law, the rich have the rich law.
If you can't afford the cheapest material, you have to see!
……
"Must kill card?"
As he listened to Professor kazel's explanation, he thought hard.
The magic guide wizard's must kill skills are generally exclusive, but there are also some systematic magic guide elves, some of their must kill skills can be common to each other, which can make the application scope of the must kill card wider, and the convenience is close to the magic card.
"I don't know if baokemeng is a system?"
"Different baokemeng can learn the same skills. Can the killing skills based on these skills be used in common?"
"For example, the skill of [carousel] can be learned by both the fairy IBU and the ball sea lion."
"And [carousel] has a continuous effect."
"There are many factors to be considered and the difficulty of refining is very high."
"What's more, you can't refine this skill if you want to..."
At the end of the day, it dawned on him.
No wonder the refining method of Bisha technology card is not described in the textbook. It turns out that it is not a mature system, but a new technology still under development.
That is, their professor is kazel, who has the opportunity to learn relevant knowledge.
This part of knowledge can be regarded as professor kazel's unique technology, which has great value.
So he took notes more seriously.
……
It's going to be over soon.
Students who understand the value of knowledge only hate time passing too fast.
The sleepy student was eager to run out at once.
lunchtime.
The students gradually forget about the homework of arithmetic class and the purchase of experimental materials. They talk about the history of magic in the afternoon, the interpretation of prophecy and the rookie competition on Saturday.
Eat and drink enough, take a nap for a while, and it's already afternoon unconsciously.
The students quickly picked up their bags, ran to the classroom, and rushed into the ladder classroom of the history of magic before two o'clock.
After experiencing the Emotionalization of the last lesson, Professor Ryan hax seems to have carried out a certain degree of introspection. This afternoon's lesson on the history of magic is devoted to some interesting stories about the journey of war, but it also brings some laughter.
At the end of the history of magic class, he collected the homework about "betrayer" assigned in the last class, and then assigned a new homework. This class is over.
"I hope professor hax can answer my doubts."
When Dake handed in his homework, he couldn't help thinking of it.
……
That night, a large number of freshmen swarmed into the library. Everyone was biting their pens, trying to solve the problem of arithmetic.
But for those who have never come into contact with this knowledge, that paper is too difficult!
In order to find out, they had to stand up and ask around, and the discussion between them was gradually out of control.
The silence of the reading room was broken, which finally attracted Ms. Bella's scolding!
Angry Ms. Bella, directly drove all the freshmen out of the library!
The seniors looked at the disheartened freshmen, and they all gave out schadenfreude laughter.
As a result, he was severely scolded.
Duck, who was also expelled from the library, had a bitter smile.
But when the avalanche, no snowflake is innocent.
He also spoke in a low voice in the reading room just now, providing a force for the destruction of the environment.
Clam, clam.
……
Duck waved to Diana and Rose: "come on, go back to the common room. Another place, you can let it go. "
Teaching people knowledge in the library, to suppress the voice, really some restraint.
It's better to be in the common room.
Diana and rose nodded.
The three left the library in frustration, and the first group returned to the common room of the noble house, quickly occupying a good place.
Then, go on with the lecture!
Although it's a lecture, there's no difference between what Professor Dake and Professor Lily are talking about, that is to say, they should be more detailed and use more straightforward language and better understand.
And one-to-two counseling can be more targeted.
Combined with the test paper issued by Lilly education, the combination of memory and application makes it easier to master.
Under Dake's patient guidance, even Diana gradually mastered the foundation and was able to solve problems by herself.
Looking at the way she worked hard, Dake couldn't help smiling a little.
Teaching and educating people is actually a matter of great achievement.
It's a good way to adjust campus life.
But when he wanted to get up, he suddenly found a pair of small eyes full of "thirst for knowledge".
The first year students of the noble house looked at him eagerly, just like lambs waiting for feeding.
So that night in the public rest room of the noble house, there was a scene that Saint Mary Ann had not seen for many years.
Almost all the first year students of the noble house sat around and listened to the second lecture of Mr. Dimon.
Senior students or come or go, all face strange looking at the group of freshmen gathered together.
Especially the blonde boy standing in the middle, let them feel some special meaning.
A few senior students couldn't help but listen in. They suddenly found that the "equations" and "unknowns" taught by Dake were things they hadn't even heard of!
So behind the first grade students, there are several more senior students.
……
It wasn't until ten o'clock in the evening that dak finished his lecture.
He sipped the apple juice from little evil beast, clapped his hands and said, "so far for today's lecture. If there is anything you don't understand, verify with each other and try to think about it as much as you can. The main thing about arithmetic is not to be afraid. If you can keep an ordinary mind when you study, they will be at your disposal. "
The first year students in the noble house nodded their heads very well.
Some even wrote down his words as a motto.
The goodwill between people is always improved by giving and accepting.
If Dake also has a "forbidden love", you can see that their favor for him has soared a lot.
The benefits of these changes can't be seen now, but as time goes by, something can always be changed.
After doing his best, he went back to the dormitory, checked the work of the wizard, and then washed and went to sleep.
This day, full of terrible!
……
The next Friday.
In the morning, the first class is duel class, and the second class is Warcraft.
In duel class, Professor Jones repeated this week's homework once again.
She asked seven students who had joined the duel club to apply for the rookie competition on Saturday morning, have at least one match, and then write a essay to analyze it.
The rest of the students will choose a player as the object, from the perspective of the audience to write a duel centered analysis essay.
But in fact, there is no need for her to repeat it many times. The freshmen of this year are even more interested in it than she imagined, and have been looking forward to the beginning of the duel.
The next section is about Warcraft.
Professor Nini actually caught another one!
When she pulled out the familiar jar from her "little schoolbag", the students who were lucky enough to escape last class suddenly turned green!
But Professor Nini is still a little proud: "the homework left last week, we finished very well. In order to make up for the missed opportunity of some students last week, we... I went to the underground city specially to catch another one. This one is bigger. It's sure to last longer! "
Then, without waiting for the students to "applaud and celebrate", she lifted the lid of the jar, drilled in two fingers, and clipped out a living spirit sucking monster!
As soon as he came out, he inhaled, and his body suddenly expanded to two meters high. His ghostly body was emitting gray smoke, and the three black holes on his twisted face were dark and deep.
Compared with the previous one meter high spirit sucking monster, it is far more than "bigger".
"Woo
The ghost is ferocious, opens its teeth and claws, and howls like a ghost.
……
……
It's four thousand today. Come on
