If there are any essential elements for the Dharma masters, in addition to the most core spiritual power, the speed and accuracy of calculations must definitely be at the forefront. After all, whether it is building a spell model, determining the direction and angle of casting a spell, and the location of the projection, as well as drawing a magic circle and preparing magic materials, all need to be accurately calculated, so no one will not care about this.

Seeing that everyone's attention was attracted, Leo said: "Actually, if you want to improve your computing ability, I personally think that the most effective way is to do a lot of targeted exercises. ”

Everyone thought he had some advanced theory, but when they heard this, they couldn't help but be disappointed and showed disdain.

"Do you need to say that?"

"yes, who doesn't know to practice. ”

"Well, I know how a country boy can have any good way. ”

Leo ignored everyone, smiled, and continued: "Of course, the practice I am talking about does not mean blind practice without a clue, it needs to cooperate with a certain special plan. In order to cope with the joint entrance examination, my teacher arranged for me to complete at least 200 questions a day, and I had to ensure the correct rate. As long as you persist for more than half a month, the effect will be very significant. ”

"Isn't this just a very common sea of questions tactic?" Mecedo questioned, "200 questions a day is not a lot, and I think many people do this exercise." In order to improve the success rate of air detection, I practiced 500 questions a day, but the current success rate is still not high. ”

Luhrmann looked at Leo, frowned slightly, and asked, "Is that all?"

Leo shook his head indifferently: "Actually, I have already said that if it is just a blind practice, it will not play a very good role, so in the middle." There are some special calculation methods that can effectively improve the calculation speed. ”

"What does the special calculation method mean?" Luhrmann was a little curious, looking at the appearance of this young man, he should not be a person who talks about it.

Leo stood up and said, "Can I show you this on the blackboard?"

Without waiting for Luhrmann to agree, Mecedo, who was very upset due to the appearance of the wiki, finally found a target to vent and said directly: "I don't think it's necessary, there is a standard process for calculation." I don't believe there's any special way to do it, so please don't waste your time. ”

"Messedo, why don't you listen to him, what if it helps?" a boy next to him persuaded.

Mercedes ignored the boy and asked Leo, "Do you think you're good at calculations?"

Although he didn't understand why Mercedes had to get along with him, Leo still replied calmly: "It should be good." ”

Mecedo sneered, walked directly to the blackboard, and wrote five questions with brushes, and in order to increase the difficulty of the calculation. He deliberately chose multiple digits.

"Now do the math, I'll see how long you need to ......"

Before he could finish speaking, Leo had already answered: "Question 112, Question 112, Question 2 985687, Question 3 133.745." Well, this fourth question is about calculating angles. 78.315 degrees, the square root of the fifth question 63, which is 7.937, I think of the last three digits. Probably enough. ”

Once again, the audience fell into a dead silence, and Mecedo was even more stunned.

"Mecedo, is his answer correct?" asked the boy next to him.

"I ......," Mecedo was stunned. Because these questions are completely random for him, he doesn't know the answers.

The long silence continued, and many people were secretly calculating those questions, but because they were really not easy to calculate, half a day passed, and they still did not get the answers.

"Bang Bang!"

Suddenly there was a loud applause, and then Vicky nodded to Leo and said, "Sure enough, it's very strong computing power, your answer is not wrong at all." ”

"All right, and so fast?"

The eyes that everyone looked at Leo instantly became extremely complicated. They have known each other for many years, and no one is unaware of the strength of the wiki, and since he agrees that the answer is correct, it must be correct.

If everyone still had a contemptuous attitude towards Leo before, after the wiki opened its mouth, there was a 180-degree change immediately. Everyone is a mage apprentice or a full-fledged mage, so they naturally know how to respect powerful people, not to mention, they are all extremely eager to learn the special calculation method that Leo said, even if the other party is just a civilian from a remote area.

"I was so dizzy, I almost missed something important, it's all on the wiki!" Mecedo was a little embarrassed and regretted it. After a moment of confusion in his heart, he wiped the question off the blackboard with a dark red face, and said to Leo: "I'm sorry for the previous question, can you please explain?"

"Absolutely. Leo accepted the other party's apology with a smile, and at the same time, his opinion of the nobles of Gaswell changed a little, it seems that they are not all the kind of people who are above the top and only know how to judge people by their status.

Coming to the blackboard, Leo said: "I think everyone will feel a lot of headaches when calculating multiplication, and many times they have to write on paper to calculate the results. ”

He then lists a simple multiplication equation and continues: "The first method, multiply two numbers within 20, add the single digit of one number and multiply the other by 10, and then add the product of the two mantissa numbers, which is the number to be obtained. ”

"In the second method, the product of the first position is ranked first, and the sum of the first and last cross products is ten times and then the mantissa product is added. ”

"The third method is different from the beginning and the same tail, one number is added to the other tail, and the mantissa product is added after the whole number is doubled. ”

"The fourth method, complementarity multiplies the number of stacks, the first place is multiplied by one, and the product of the mantissa is followed by the number. ”

"Fifth Method ......"

After a short time, Leo finished introducing several speed algorithms in order to cope with the college entrance examination study that year.

One girl was pleasantly surprised: "Wow, it's so much easier, but it's just a simple multiplication, what if it's complicated? And division?"

Leo smiled at the girl and said, "Next, I will introduce you to several complex multiplication and division calculations, but they may not be so easy to understand. ”

............

Half an hour passed, no one interjected, and at this moment everyone became attentive students, even Luhrmann kept gesturing with his fingers, learning the various quick calculations introduced by Leo.

As a person who has studied mathematics, of course, he knows that if these calculation methods are integrated, it will indeed be of great help to improve the calculation ability and accuracy, and it is not easy to summarize so many special calculation methods, not only to have excellent analytical power, but also to spend a lot of time on research.

"How old is this kid to be able to study these calculations, hehe, His Highness is really very discerning. Luhrman secretly thought that if it weren't for Alice's deposit, he would definitely have to go and woo Leo immediately.

When the last method was finished, Leo said: "Actually, the calculation method I have introduced still requires a lot of practice over a large distance. However, in the calculation process, the clever application of special calculation methods can still help to improve the speed and accuracy. ”

Only then did everyone react, and the explanation was over.

Mecedo took the lead in applauding and said, "If it weren't for listening to your explanation, I really can't imagine that so many special methods can be summed up in the original calculation, thank you." ”

"Nothing, I also want to be able to be on the road of magic and never be alone. Leo bowed down to thank everyone for the applause and slowly walked back to his actions.

Mecedo hesitated, but finally couldn't resist his desire to learn, and turned his head and asked, "Grandpa Ruhrmann, when the salon is over, can you ask the clerk to help me transcribe a transcript of the lecture just now?"

"No problem. I'll ask the clerk to make a copy of each of them for everyone to go back and study. After Luhrmann finished announcing, he looked at Leo again and said, "These calculations of yours are wonderful, I want to put them together and send them to the Junior Mage Weekly, I think they will be happy to publish such an enlightening summary of the calculations, what do you think?"
