Early the next morning, a group of wizard apprentices entered the examination room with trepidation. After receiving their own test papers, they quickly began to calculate with frowns.

Peirce did not dare to delay and glanced at the first question.

【A and B start from two places at the same time and walk towards each other. After four hours, they meet at a distance of 5 kilometers from the center. It is known that A's speed is faster than B's. How many kilometers per hour is A faster than B?】

Peirce frowned suddenly. This should be a math problem, to find the unknown variable, but there are not many conditions given. After thinking for a while, he finally came up with an idea to solve the problem and began to draw a line graph.

On the other side of the examination room, several wizards in charge of invigilating were also looking at the test papers in their hands.

Fulla and others were very interested in the graduation exam of the Iyeta School, so they volunteered to supervise the students and also became interested in doing the questions.

Originally, Fulla thought that these questions were prepared for apprentices and would be easy for a formal wizard like herself. But after looking at a few questions in succession, she was dumbfounded.

"Is this what Yieta College teaches on a daily basis?" a wizard asked in confusion. He thought the exam would be about elements, herbs, alchemy and shaping.

"Not bad!" Lin En nodded, looked at Fula and the others, and said, "In general, there are three subjects: Mathematical Olympiad, Chemistry, and Physics... In the future, we may add Biology."

"But what's the point of learning these? It's better to learn a few more magic spells with the time..." Fulla curled her lips.

Lin En straightened his face. "Mathematical Olympiad is the foundation of all natural sciences. Chemistry is the study of the composition, structure, and changes of magical elements. As for physics, it is the exploration of the laws governing the operation of the world..."

"The purpose of studying these courses is to explore where magic comes from!" Lynn said firmly.

Where does magic come from?

Hearing this, everyone present was shocked. Although they had studied magic in the past, they seldom thought deeply about this issue.

Lin En continued, "As for their functions, I think you have seen them, right? They are everywhere in the city! The glass, paper, airships, ships, and even electromagnetic railguns you see can all be classified into these three disciplines!"

Thinking about what she had seen and heard since entering Yieta, Fulla put away her original contemptuous thoughts and began to examine each question seriously.

However, since I had never systematically studied Olympiad mathematics, I really didn’t know where to start to solve these equations, so I had to look to Lin En for help.

Lynn raised his hand and tapped lightly, creating a soundproof barrier nearby, before explaining.

"This problem is actually very easy to calculate. It's just a little bit complicated. If A and B have the same speed, then they will definitely reach the midpoint at the same time. However, they met 5,000 meters away from the midpoint. Therefore, A, who is faster, must have traveled twice as far as B, which is 10,000 meters."

Lin En explained his idea of ​​solving the problem as concisely as possible. This problem is actually not difficult and can be solved with a little thinking.

The test paper he gave had a total of fifty questions, each worth two points, with a total score of one hundred. Sixty points was considered a pass, which meant that only thirty correct answers were needed! The difficulty of these questions was also carefully designed by Lin En. There were twenty-five "easy" questions, twenty "simple" questions, and five "more difficult" questions.

According to his expectation, if Alok and others had taken notes seriously, it should be easy for them to answer all the easy questions, and then they only needed to answer five "simple" questions correctly to pass the exam.

However, this is just a passing grade. Lin En hopes that there will be a few students with excellent grades who can be trained intensively. These are all talents in scientific research.

Of course, in addition to the "liberal arts" exams, these students also have to take a practical course to test their actual combat and basic spellcasting abilities. The average of the two is added to determine whether an apprentice is qualified to become a formal wizard. This is also to give some students with some weaknesses in one subject an extra opportunity.

After Lin En explained a few Olympiad math problems, Fulla and the others quickly realized the fun of doing the problems. They started to ponder with their pens in hand, completely forgetting that they were there to supervise the students' exams.

For Orlando, these "easy points" questions were naturally nothing. After glancing at them, he turned his attention to the questions on the test paper that were marked as easy by Lin En.

[A wizard driving an airship encountered an accident and jumped from a height of 480 meters. After free falling for a distance, he performed a slow fall spell and decelerated at a constant speed of two meters per second. When he reached the ground, his speed was exactly zero. Without considering air resistance, calculate the total time of the fall and the distance of the free fall...]

Well, this should also be an equation problem.

Orlando thought about it. He remembered that Lin En said that free fall motion is uniformly accelerated linear motion with an initial velocity of 0. The formula is v=gt. G is the acceleration due to gravity, which seems to be 10 meters per second? What is this t? It should be time?

But the falling body is divided into two parts, the time and distance of the fall are unknown, and the answers need to be found. Simply applying this formula will definitely not work...

Orlando pondered for a long time, with cold sweat on his forehead.

He found that he couldn't do it! "Dean Lin, these questions are too difficult, aren't they?" Orlando couldn't help but remind him. You call this a simple question? Is this really a question that an apprentice should do? He thought this was a bit too outrageous.

"Is this difficult?" Lin En looked at Orlando strangely. He remembered that he had explained the relevant formulas before and published them in the [Magic Daily] so that wizards and even townspeople who were interested in studying mathematics could enjoy the fun of the Mathematical Olympiad.

Moreover, each wizard is equivalent to a humanoid computer. Even an apprentice's computing power is much stronger than that of an ordinary person. These questions should be within an acceptable range.

Just as Lin En was about to explain, his expression suddenly changed. He stretched out his hand and snapped his fingers. The magic power in the area around him surged. In an instant, a copper nail flew out and nailed to the feather pen and test paper held by an apprentice with lightning speed...
