A person's brain logic is very important because it has a great influence on his behavior and judgment of things. If a person can't cultivate his own logic well, there may be some problems in his future behavior and attitude. Therefore, the purpose of learning mathematics knowledge is to better enable us to do things step by step, rather than creating a bigger span. Just like a big goal, our thinking logic in mathematics is to dissolve the big goal into many small goals. When we overcome all the small goals, the big goals are disintegrated by us. This is what we call big and small, small and nothing.
Mathematics has a great influence on the cultivation of our thinking logic and our future habits. Generally speaking, people who are good at math are better at organizing and handling things than those who are poor at math. But it doesn't mean that people who are good at mathematics will have a broader future. Mathematical thinking only has a certain influence on one's own thinking when dealing with things. However, different behaviors and attitudes that different occupations need to deal with also have considerable influence. So learning mathematics is helpful for future life and work.
Maybe math knowledge is seldom used in our real life. However, the application of mathematical thinking logic in our future study and life is still very broad.
