120 minutes to solve the math problems in the college entrance examination.
1. Make good use of the five minutes before the exam.
Candidates will get the math paper five minutes before the mid-term exam, but they will not answer it. However, these five minutes are also important.
One way is to browse and choose a math problem for 5 minutes first, and decide whether to choose polar coordinates or inequalities. Do the math problem first when you start the exam, and you won't panic if you get 10, so as to avoid having no time to do the math problem at the end.
The second method is to work out the first two simplest questions in your mind, and get 10 directly when you start the exam.
2. Control time. The total score of college entrance examination mathematics is 1.20 minutes, with an average of 3 minutes for each course. Try to get the answer in one minute, try to score 80 points in about 50 minutes, and ask for accuracy once. Don't spend too much time on individual small problems.
At the same time, we should pay attention to the combination of various methods in small questions, such as the combination of numbers and shapes, special values (including special values, special positions and special figures), elimination, verification, transformation, analysis and estimation. Once the thinking is clear, we will answer quickly.
The college entrance examination is not entangled in one problem. You can mark it first, or get the answer by using special values and other methods, and then you can overcome it later.
Introduction to mathematics
Mathematics [English: Mathematics, from ancient Greece μ? θξμα(máthēma)； Often abbreviated as mat], it is a discipline that studies concepts such as quantity, structure, change, space and information. Mathematics is a universal means for human beings to strictly describe and deduce abstract structures and patterns of things.
It can be applied to any problem in the real world, and all mathematical objects are artificially defined in essence. In this sense, mathematics belongs to formal science, not natural science.
Different mathematicians and philosophers have a series of views on the exact scope and definition of mathematics. Mathematics plays an irreplaceable role in the development of human history and social life, and it is also an indispensable basic tool for studying and studying modern science and technology.
