Ah Jin Is Punished Every Day

Ah Jin was once a young and ignorant man who worked as a gangster. After changing his mind, he devoted himself to the sunshine. Finally, he chose to join the most powerful sect in the world - Xuezong. Because I admire the powerful and powerful Mathematical Immortal, I want to learn from the Mathematical Immortal and become more optimistic! Ah Jin tried his best to hug the Mathematics Fairy's thigh and study the math method with all his strength. Unexpectedly, the Mathematics Immortal has actually been possessed by the devil for a long time. Mathematics Immortal (snorted coldly): "How can anyone not be possessed by mathematics?" He forced Jin to do all the things he thought were impossible in this world, such as from the neck down, such as... So one day, the Immortal of Mathematics smiled evilly, looked at Ah Jin who was pitifully tortured by him, and asked: "Does Jin want a logarithmic function with a base greater than one today, or a logarithmic function with a base between zero and one?" Ah Jin had never been exposed to such a profound number method, so he was afraid and confused and said: "Master, it... Is there any difference between them?" Mathematical Immortal: "One curves upward and one curves downward." Ah Jin: "A Jin chooses the one who is better!" Finally, when Ah Jin was babbling in the plane Cartesian coordinate system with tears in his eyes, he realized that both of them are infinitely long... Intention: Sunny and cheerful, study hard and make progress every day
