"Mathematics? Complicated and useless. Why do you have to learn so much? Maybe you should draw a parabola to learn when you go to the vegetable market to buy food after graduation? Mathematics ... it's almost the same after finishing primary school, and those who are deeper are left to mathematics majors to learn. "

I don't remember which book I read this speech in. Although it caused quite a stir among my classmates at that time, there were still a large number of people who insisted on "forgive and disagree" like me.

Do you really have to finish primary school mathematics to live a good life? As far as the current social situation is concerned, "good" is not necessary, but "life" is not a problem. Isn't there a lot of people with primary school culture living normally in today's society? It seems to be unaffected by mathematics.

But mathematics is useful after all, at least I believe and firmly believe this.

At a shallow level, we study mathematics initially in order to successfully pass the senior high school entrance examination, and secondly in order to successfully pass the college entrance examination, go to a good university, and get a stepping stone to find a good job. Mathematics is not the only subject, but at least it accounts for a large proportion, and almost no one dares to say lightly, "I can still go to a good university without studying mathematics."

Secondly, every subject is related, especially for the subjects that are partial to science. If you do poorly in math, physics and chemistry are not much better. Although there is no scientific basis, from my observation, it seems to be true.

Mathematics can not only help you get a good grade, but also create a kind of rational thinking, which not only promotes the partial scientific discipline, but also permeates into daily life, allowing us to judge problems with a more rational thinking, so that our eyes on things can not only stay in words.

Looking at mathematics with a worldwide pattern is not without its merits.
