I think you mean pure mathematics! Because almost all majors and everything are inseparable from mathematics. Business in life, the quantity of food and cooking, financial statistical analysis at work, etc. However, I think this question cannot be answered in general. There are too many people in China! 1400 million! Is everyone good at math? If all China people are good at mathematics, then China people are good at mathematics (mathematics is definitely useless in China at this time), and if China people are not good at mathematics, then China people are not good at mathematics. This is obviously a fallacy! I studied basic mathematics in college! If you answer objectively, mathematics is still very useful, but it is useful for the rich and those who have the ability to start experiencing life (except those who specialize in mathematics, of course). Because most people in life have to work for a living all their lives, however, compared with other majors, it is not easy for pure mathematics majors to find a job.

If a person begins to know how to enjoy life and stop working hard for a living, I think he will think about improving his math ability at this time, because learning math can not only improve his math calculation and estimation ability, but also improve his logical thinking, reasoning and judgment, and debating thinking ability. This is the best embodiment of the wonderful use of mathematics!
