One of the students went to the door to open it, but found the principal's words to be true and the door was locked tightly. "Kamali" runs to the window to see if someone can help, so she tries to open the windows but in vain. She screamed at the top of her voice so that the guard outside could hear her, but she finally realized that the glass was soundproof and so was the picture because the guard did not see what was happening inside, even though he was close to them.
Some of them tried to use force to break the door, but they did not succeed in that, so they realized that the only solution was to solve the problem to get out of the test, and most of them intended to withdraw after completing mathematics. "Sami" spoke after a long silence to say that the exit is not the same as the door we entered through, and he knew that by analyzing the words of the director when he said that solving the problem is the only way to find the exit and he did not say to open the door, meaning that he meant another exit. Time was passing and the students were still confused by the strange situation and did not start to complete the test and did not understand where the problem was yet. The optimists of them thought that it was just a pedagogical experience and that it would be an entertaining adventure that they would tell about after it ended. As for the cautious students, they realized that they had entered a game that they did not know how dangerous it was, nor its rules, and how it would end. But the best thing is that they work together to get out of the same problem and this has increased their confidence in success.
"Adam" calmed the students down as usual and asked them to consider taking the test because it was the only solution they had. "Kamil" advanced towards the electronic screen that indicates the countdown to the time of the exam and tried to find any clue about the test subject or the solution, but he found a warning written in small font saying: "If the exam time has passed and you do not leave the room, you will not be fine afterwards." The student was a great deal of shrewdness and acumen and was fond of informatics and modern technology, he did not want to confuse his colleagues, so he decided not to tell them this warning and started thinking about saving everyone from this suspicious situation. Adam puts the students in groups around the room and asks "Sami", "Kamil", "Lydmila" and "Tamara" to lead the groups since they are the best math students. Everyone was looking for any equation or engineering drawing to be the focus of the exam. "Lydmila" asked everyone to put themselves in the professor's shoes and to imagine which theme the exam might be. After a minute of thought, everyone looked at each other and remembered their teacher's emphasis on the axis of the arrays.
This lesson was one of the most important things the students learned due to its many applications in reality. Distribute the students to search for matrix equations and then find their solutions and represent them graphically.
The students set out looking for the problem equations for the matrix. One of the students accidentally tore the wall covering to find a tightly closed door in it that can only be opened with a password, which is a graph that represents the solution of the equation. The students knew that they must find the three functions to open the door that was in the back wall of the department, not the door. From which they entered the background of all the students to find the functions, and they found only two. The excellent students in mathematics began solving the two functions. A team of three people each, while the third team kept looking for the third function, and it was the most difficult. The meditating student was still noticing his colleagues. The one who spoke to him and was known for his talent, saying, "Don't you see that everyone needs you, why don't you do something?" He answered very calmly that the last function is on the floor or in the ceiling, and there are signs that indicate it. He did not depend on an accident, but the walls were not in vain. Rather, it was thoughtful for his colleagues. Finishing the two functions first was his colleagues. In two teams accelerating the time, the graph of each function after they successfully complete the task, there is only one function left. . The drawing was not completed, and a part of it remained, which is the solution to the last function. Smart asked his colleague illustrator to project the graph on the hall, depending on the location of finding the two functions as the starting point. His colleague did it professionally and was able to predict the trajectory of the curve in effect by projecting onto the surface of the walls, floor and ceiling. The rest of the students follow the path determining the starting point of the third function. A student could feel a shaky slab on the ground to pull it out and find the sign written on its underside. Their joy did not last long, and the ink with which the function was written was gradually disappearing. Each student memorized a part of the function before the ink disappeared, and re-wrote it with a stone, and the intelligent student began to solve it. All eyes were on him and everyone was counting on him to get rid of the math exam. He didn't care about anyone's looks and he knew very well that time was coming to him and only a few minutes remained. The student used all his intelligence and all his strength trying to get rid of the exam and rid his colleagues The tension appeared on all the students as everyone was He is unaware of his fate if he fails the exam. It's almost time, the countdown to the last five minutes of exam time has begun. The student finally raised his head and said this is the solution. His colleague quickly took it and drew the third graph on the board one minute before the time was up. The door opened automatically and the students rushed out, hardly believing what they had gone through, and they thought that they had managed to get out of this nightmare and would not complete the rest of the exams. The students came out first one after the other and the rest of the students followed them before the door closed automatically after one minute of opening it.
