1. Quotes about mathematics
Russell said, "Mathematics is symbols plus logic".
Pythagoras said, "Number governs the universe".
"Mathematics is an art of ingenuity," Halmos said.
2. Interesting math stories
During the Warring States Period, King Qi Wei and the general Tian Ji raced horses, and King Qi Wei and Tian Ji each had three good horses: upper horses, middle horses and lower horses. The race is divided into three races, with each horse being wagered on a thousand gold.
Since the horsepower of the two is almost the same, and King Qi Wei's horse is better than Tian Ji's corresponding level of horse, so most people think that Tian Ji will definitely lose.
However, Tian Ji adopted the advice of the doorman Sun Bin (a famous military strategist), and used the dismount to match the upper horse of King Qi Wei, the upper horse to the middle horse of King Qi Wei, and the middle horse to the dismount of King Qi Wei, and as a result, Tian Ji won a thousand gold by defeating King Qi Wei 2-1. This is an example of China's ancient application of the idea of countermeasures to solve problems.
3. Encyclopedia of Primary School Mathematics Formulas
The commutative law of addition: the addition of two numbers to exchange the position of the added number, and the sum is invariant.
Associative law of addition: add three numbers, add the first two numbers first, or add the last two numbers first, and then add the third number, and the sum is unchanged.
Multiplicative commutative law: When two numbers are multiplied, the position of the exchange factor and the product remain unchanged.
Multiplicative associative law: multiply three numbers, multiply the first two numbers, or multiply the last two numbers first, and then multiply the third number, and their product remains the same.
4. Mathematics problem-solving methods
When we encounter math problems that we don't know, a particularly useful method is to draw a picture, which is suitable for multiple-choice problems, because there is no need for a calculation process, and the correct answer can be directly selected. Some problems in mathematics may be troublesome to calculate with formulas, or some students will not do it step by step, but they can often see the answer immediately after drawing the picture, and it also saves time to do the problem, which is very efficient.
When you don't know how to do this problem, you can substitute each option into it, and use the test value method to solve, 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 into the test.
5. Mathematics learning methods
Before the class, a preview session is essential. First sort out the undergraduate knowledge structure, it doesn't matter if you don't understand it, but you must know what the teacher is going to talk about in this class.
When you practice for the exam, you will record the knowledge points that you have mastered badly, and review the materials in time. If you encounter the knowledge points you have learned before, read the textbooks and materials, and ask others for advice in time. After understanding, you can find some derivative or variant questions to consolidate.

ab=18 AB is divided into three equal parts from AC=2BC, from D is the midpoint of the line segment AB, E is the midpoint of the line segment CB, and DE=6 gives 3DE=AB, so AB=18
First of all, let's analyze this diagram: from a on the positive half axis of the y-axis, we can know that c must be positive. Since one of the corners of this parallelogram is known, we can find the left side of the three points of abc, which is represented by b c. >>>More
