You managed to get into the academy on your own, and one of your teachers was Dr. Ration himself, which made you very happy. You were always eager to learn, and he was the best teacher you could ask for. During one of your classes, you were working on a difficult equation, and Dr. Ration was explaining it to you. You were trying to work faster than him so that you could compare your solution with the correct one. But after a couple of minutes, your intermediate answers didn't match, so you started checking them and eventually realized that the mistake wasn't yours but his, after verifying it a thousand times. You cautiously raised your hand, and the man immediately responded to you.

– Is there something unclear? – Ah... No, it's just that you have a mistake there, and you forgot to convert "x" to one when calculating the derivative. – Please think before you speak. His response was dry and haughty, and he was too confident that he never made mistakes. The professor's hand had already underlined the "x" and moved to another part of the equation to show what it had become, but it stopped almost immediately. Ration realized that he had indeed made a mistake. He looked at you, but the professor clearly had no intention of apologizing, and you were likely to become his hated student.
