Why do you have to take a math test for the postgraduate entrance examination? Is mathematics that useful? I have worked for many years, making hardware and software, and never used calculus? Why should I take the postgraduate entrance examination? Hello, I'm a freshman now, and I feel good about advanced mathematics. I've had your confusion before. But after I went to college, I thought about it carefully. Actually, math is really useful. The usefulness of mathematics lies not in the knowledge points of mathematics, but in the various ways of thinking mentioned in mathematics, which can greatly affect our lives. You can try to treat everything in life with the logic of learning mathematics, but that may be boring. Secondly, mathematics also cultivates people's research spirit and analytical logic ability. I hope you can study mathematics with an optimistic and positive attitude, think more and summarize more. I wish you success!
