1, a famous saying about mathematics
Russell said, "Mathematics is symbol plus logic".
Pythagoras said, "Numbers dominate the universe".
Halmos said, "Mathematics is a unique art".
2. Interesting math story
During the Warring States Period, Qi Weiwang and Tian Ji raced, and Qi Weiwang and Tian Ji each had three good horses: getting on, winning and dismounting. The race is divided into three times, and thousands of dollars are bet on each horse race. Because the horsepower of the two horses is almost the same, and Qi Weiwang's horse is better than Tian Ji's, most people think that Tian Ji will lose.
However, Tian Ji took the advice of his disciple Sun Bin (a famous strategist) and dismounted Qi Weiwang's horse, Ma Zhong of Qi Weiwang and Qi Weiwang. As a result, Tian Ji beat Qi Weiwang 2-/kloc-0-and won a lot of money. This is an example of China's ancient substitution game theory to solve problems.
3, the primary school mathematics formula daquan
Additive commutative law: Two numbers are added to exchange the position of the addend, and the sum remains the same.
Law of addition and association: when three numbers are added, the first two numbers are added first, or the last two numbers are added first, and then the third number is added, and the sum is unchanged.
Multiplication and exchange law: when two numbers are multiplied, the position of the exchange factor and the product remain unchanged.
Multiplication and association law: when three numbers are multiplied, the first two numbers are multiplied, or the second two numbers are multiplied first, and then the third number is multiplied, and the product remains unchanged.
4. Mathematical problem solving methods
When we encounter a math problem that we can't understand, a particularly useful method is drawing. This method is suitable for multiple-choice questions, because we can choose the correct answer directly without calculation. Some problems in mathematics may be troublesome to calculate by formulas, or some students will not do them step by step, but they can often see the answers immediately after drawing a picture, which saves time and is very efficient when doing the problems.
You can also use the trial value method to do math problems, which is also more suitable for multiple-choice questions. When you don't know how to do this problem, you can substitute each option and solve it by trial value method. If the correct answer is in the front, the speed of doing the problem will be very fast. If the answer is in the back, you need to substitute each value and try again.
5, mathematics learning methods
Preview before class is essential. First, sort out the undergraduate knowledge structure. It doesn't matter if you don't understand, but you must know what the teacher is going to say in this class.
Record the bad knowledge points when practicing the exam at ordinary times and review the materials in time. If you encounter knowledge points you have learned before, just look through textbooks and materials and ask others for advice in time. After understanding, you can find some derivative or variant topics to consolidate.
