There are some things in life even if you are not interested, they must do it. Do not underestimate the usefulness of mathematics. Mathematics is the basis of science and engineering must. Many students see college major in mathematics do not ask, immediately relieved, Because they think of mathematics in high school is the hardest, and most see the application or employment prospects. However, many science and engineering are based on the mathematical basis of science and engineering mathematics is required. Many students see University specializing in mathematics ask for much, just a sigh of relief, because they think of mathematics in high school is the most difficult to learn, but most see the application or employment prospects of discipline. However, many science and engineering study are based In mathematics, for example, on the basis, in order to learn solid computer engineering, at least make discrete mathematics - including set theory, graph theory, mathematical logic, linear algebra, probability and statistics, mathematical analysis to learn; if you want to read Dr. computer or master, it may also require a higher mathematical basis. In addition to the professional requirements, mathematics is thousands of years of human wisdom, learning mathematics can train and exercise a person's thinking ability by studying geometry, we learn how to use deductive reasoning to verify and thinking; by learning probability and statistics, we can learn how to avoid entering the dead end of thinking, how to maximize their opportunities so be sure to carefully learn mathematics, not half-heartedly in the choice of learning mathematics methods. The most important thing is not many elective math course, but to know "why" of learning, from learning to master a way of thinking at the same time, thousands of years of accumulated human mathematics is wisdom, learning mathematics can train and train . man's thinking ability by studying geometry, we can use deductive reasoning to verify and learn methods of thinking; opportunity to learn probability and statistics, we can know how to avoid the dead end drilling thinking, how to make in front of their biggest technology. Therefore, we must learn the intentions of mathematics, not perfunctory.
