I Am Not A Mage Lord

　　　　 At noon at the lunch restaurant, Lynch and other freshmen all appeared one after another on the ring restaurant of the North Castle, sitting by the window, and even able to watch the lush forest landscape outside the Star Boundary Island.

　　Because the food provided in the restaurant contains a lot of refreshing herbs and memory-stimulating medicines, the apprentices will show up on time when they forget to eat or sleep.

　　 However, at this moment, the entire restaurant also appeared in a scene comparable to the final battle of the third year of high school.

　　 The mathematicians without mathematics chewed on the food that seemed to be drenched in curry sauce, while watching the large book next to them, they were muttering words.

　　 The "big tome" in everyone's hands is much thicker than the modern Chinese dictionary. When you look closely, it is a table full of numerical values ​​like excel.

　　 This is a "common logarithm book", and finally there is an appendix of the trigonometric function table. After the "Mystery Field Theory" course is over, the master apprentices will have one.

　　 Logarithm, when it appeared in high school mathematics class, the algorithm after this power subverted the thinking of many high school students and made mathematics lose its intuition for the first time.

　　 But it was on the Blue Star, but it was once praised as the three major achievements of the 17th century along with analytic geometry and calculus.

　　 Even the famous Laplace classmate praised it for "greatly prolonging the life of astronomers."

　　 Yes, in that era without modern computers, astronomy for the purpose of precise measurement encountered a series of huge and complicated numbers. It may take a year and a half to calculate a simple planet position by accident.

　　 is only for calculation.

　　 until the appearance of the logarithm.

　　 It can turn complex multiplication and division into the most basic addition and subtraction.

　　, for example, find the value 8.134x4.252.

　　 Check the logarithm table lg (8.134) = 0.9103, lg (4.252) = 0.6286.

　　 Then add 0.9103 and 0.6286 to equal 1.5389.

　　 Then look up the logarithm table and look up the 1.5389 power of the table 10 = 34.5859, this is the result of the multiplication.

　　 But in fact 8.134x4.252=34.585768, the gap is already very small.

　　 The whole process is logarithm check-addition-logarithm inverse check, three steps.

　　 In fact, if a dozen numbers are multiplied together, it is a dozen times of addition.

　　 This is where the natural logarithm table really shines, and division is the embodiment of subtraction.

　　 So a logarithmic table from lg (0.0000) to lg (9.9999) solves the problem of multiplication and division of extremely large values ​​that has been difficult to handle for thousands of years before the advent of computers.

　　 The trigonometric function table has the same principle. It is much more convenient to memorize the actual value of each angle directly than to calculate the specific angle value with the trigonometric formula.

"How can I recite this?" Apprentice Mo Yifei quickly wiped the curry sauce on the logarithmic table, and immediately couldn't help but grab his own hair. He was from an ordinary family and wanted to prove himself, but he was helpless. .

The apprentice Liu Kai shook his head, "Don’t get entangled, hurry up, or I’ll see you in the "Mystery Field Theory" from now on. I just inquired about it, and it's the same throughout the school year. This is the first way of mystery field theory. Stop the road."

　　 All the students in the restaurant couldn't help shaking their heads and smiling.

　　 The next moment they received this "Common Logarithm Table", they also received an unforgettable notice.

　　 During the next period of time, the "Logarithmic Calculation Test" will be open in the lobby on the first floor of the "Basic Library" in the North District, and you can challenge 10 times per natural month.

　　The pass criterion is to answer 20 complex calculation questions with a 90% correct rate in 1 minute, so that they are eligible for the next "Secret Energy Field Theory" course.

　　 This test, whether it is born with excellent calculations or with excellent memory, each has an advantage, so many self-confident talents are gearing up to wait for the official test to start at 8 o'clock tonight.

　　 If it can't be completed within a month, then it will really have no face to stay in the academy.

　　 Not to mention that if you fail to pass before the end of the semester, you will be sent back to your place of origin and become an apprentice to a former mage.

　　 Looking at Lynch, who is both tangled and expectant, has a subtle mentality.

　　 On the one hand, when he turned over the entire "Common Logarithm Table", it lay quietly in Lynch's memory palace.

　　The key to the problem is that he can indeed memorize it without painstakingly, saving ordinary people's time and effort over the years.

　　 Because the logarithm table is purely a series of numerical values, there is at least the context in the recitation of the text. There is no memory knack at all, and it is even more boring than recitation of the hundreds of Pi.

　　 Shan Lynch suffers from the inherent time that is wasted during specific reading.

　　 There are 20 questions in 1 minute, with an average of 5 seconds per question.

　　 For those with strong memory, it is necessary to use a logarithmic table to complete a series of additions within 5 seconds.

For those with strong calculations, if the logarithm table is incomplete or even the numbers have errors, they must use their own calculations to make up for it, such as a few laps to get the specific logarithmic value, which is equivalent to completing a series of additions in 5 seconds. And complex calculations that are difficult to predict, including some recall time.

　　 And Lynch, it was the result of "Memory of Logarithmic Tables" in the Palace of Memory.

　　 The key is that he has to find the value he wants from the dense logarithm table, and it takes at least a second.

　　 Not to mention and his addition and subtraction is still not dominant.

　　 Really add dozens of digits, how can he figure it out in a few seconds, and the time for drafting in the palace has run out.

　　3 minutes, he must pass properly.

　　 1 minute, he is a little troublesome.

　　 Lynch has a headache, and even the thought of exploring the dragon egg and studying how to use it as a sensor is a little weak.

　　 Just now, he tried to bite his teeth, the wind was blowing and shaking, the egg body remained calm, as if waiting for him to actively feed the runes.

　　 At this time, Zhang Quan, the head of the second-year student house, also arrived at the end of the morning class, and he came over to look for the care of these new rookies with the dinner plate.

　　 Seeing everyone's frowning expressions, he laughed on the spot, "I almost forgot about it. At that time, I was stuck in a test that took more than a month and almost scared me to death."

　　 "Leader, did you not get the reward?" Liu Kai immediately continued.

　　 If this test is passed within one month, certain points will be awarded.

On the first day, the highest score was awarded by 10 points, and then it slowly decreased, until the last week it was only 1 point~www.wuxiaspot.com~Zhang Quan's expression was embarrassed for a few points, and then he lowered his voice, "Come on, you still think the college is true So generous? Let me be honest, at least half of the apprentices passed without points after a month."

　　 "Because the test questions are gradually decreasing over time." Zhang Quan said and pushed his flat frame for the gentle temperament.

　　 "Every year, there are tens of thousands of apprentices in the entire North District, and they can pass on the first day, no more than two palms. The complexity and disgusting degree of the subject are beyond your imagination."

"So we ordinary people, we just wait until the difficulty becomes low before going. Otherwise, it will be the fate of cannon fodder at the beginning, and we will be simply beaten. Of course, if you have the genius to recite the logarithm table today, then it should be. I did not say."

　　 Hearing this, Liu Kai faintly worried that he would hang in this department, and he patted his chest with confidence. Suddenly, the meal on the plate was fragrant, and the roommates at the same table also smiled.

　　 It was Guo Sifei, Zhang Ye and other struggling factions, who continued to gritted their teeth and looked at the logarithm table, and remembered it hard.

　　 Suddenly, another group of people from the dormitory came over and said, headed by the tall man, "Who is classmate Lynch?"

　　 Seeing the unkind people coming, the roommates around suddenly stood up. In the college, there is no class division system, so everyone’s sense of collective honor comes more from the ease in the same dormitory.

　　 The tall man snorted, "It's nothing, it's Zhang Qi, the boss of our North 12th dormitory. I want to take a gamble with you on this test."

　　 "Huh?" Lynch raised his eyebrows silently.

　　 "The bet is very simple. Naturally, the one who passes first wins." The Gao Zhuang apprentice looked smug.

　　 "As for the loser, he will not be allowed to take the test this month."
