Two. Ten. 4. Math fill-in-the-box game.

There are liberal arts mathematics, science mathematics.

The math in life is as follows:

1. Calculation of wages. Financial income and expenditure, daily consumption management, etc.

2. Mathematical addition, subtraction, multiplication and division calculations. Such as the purchase and sale of goods, the calculation of date, the calculation of time.

3. Calculation of area. The size of your own house, the area of the park, the playground and so on.

4. When riding a bicycle, use your foot pedal to pedal the number of meters traveled by the bicycle. We can measure the radius of the wheel and find it using the formula for the circumference of the circle.

5. Calculation of family living costs, after learning mathematics, it will be used involuntarily in life. It is often used to coordinate the method, such as the sequence arrangement of a series of things in the process of cooking, which is based on the knowledge of mathematical sciences.

6. For computer-related workers, mathematics is indispensable in their work. If you write a program in C, you need to use sorting algorithms (such as quicksort, insert sort, heap sort, merge sort, cardinality sort, Hill sort, bucket sort, tournament sort, etc.).

1. The application of mathematical geometry knowledge in life

Mathematics has gradually become the main tool for designing and constructing diagrams, which is not only an intellectual resource for architectural design, but also an effective way to reduce technical errors and construction experiments.

Proportion, as well as the layout, balance and scale that are closely related to proportion, are all important factors in the composition of architectural aesthetics. The correct and harmonious scale and proportion belong to the main conditions for reflecting the building structure, especially the application of the first division ratio can make the beauty of the building reach the extreme.

2. The application of mathematical and statistical knowledge in life

Statistical work, statistics and statistical science. The relationship between statistical work, statistical data, and statistical science is that the results of statistical work are statistical data, and the basis of statistical data and statistical science is statistical work, and statistical science is not only a theoretical summary of statistical work experience, but also a principle, principle, and method guiding statistical work.

3. The application of mathematical inequalities in purchasing

Go to the fruit store to buy apples, buy apples in a different way: spend the same amount of money every time, no matter what the apple's ** is, only buy apples for so much money; Buy the same weight of apples every time, regardless of the apples. Well, there may be a question raised:

In the case of the same number of purchases, which way to buy apples has the least average **, which involves the application of inequality.

4. The application of mathematical probability knowledge in life

It reflects the likelihood of a random event. A random event is an event that may or may not occur under the same conditions. Probability is widely used in life, such as the estimation of **, sports lottery, factory defective rate, etc.

For example, from a batch of ** and defective goods, randomly draw a piece, "draw is **" is a random thing. Suppose n experiments and observations are carried out on a random phenomenon, in which event a occurs m times, that is, the frequency of its occurrence is m n. After a lot of trial and error, it is common for m n to get closer and closer to a certain constant.

5. The application of mathematical interest rate knowledge in life

The credit card channel returns the funds within the period specified by the bank, and once the specified period is exceeded, interest is charged according to the length of time. In the process of calculating the interest, the mathematical interest rate will be used, and if you are proficient in this knowledge, then you can calculate the charging standard of the credit card of major banks in terms of overdue interest through the mathematical interest rate.

Mathematics is everywhere in life, and all bridge buildings, seat bench design, and home decoration design are all based on the geometric foundation of mathematics.

Mathematics is everywhere in life. The time indicated by the traffic light is mathematics, the production is everywhere mathematics, and the ** of buying and selling goods is also mathematics.

1. The fan blades of the fan rotate around the center and there are countless straight lines.

2. Triangular bracket: The triangle has stability.

3. Quadrilateral sliding door: The quadrilateral is unstable.

4. The functional relationship between speed, time and distance.

5. Use coordinates to represent geographical location.

6. Whether you can win the lottery if you buy a lottery ticket, the probability is a problem.

7. Kite flying smoothly is an application of the properties of axisymmetric figures.

Learning mathematics is to be able to apply it in real life, mathematics is used by people to solve practical problems, in fact, mathematical problems arise in life. For example, you naturally need to use it when you go shopping on the street.

I once saw a report in which a professor asked a group of foreign students, "How many times do the minute and hour hands coincide between 12 and 1 o'clock?" The students took their watches off their wrists and began to dial the hands; And this professor is giving.

When the same question is asked, the students apply.

Since then, I have consciously connected mathematics to everyday life. Once, Mom.

You can put two pieces of bread in the pot. I thought, isn't this a math problem? It takes two minutes to bake a cake, one minute each for the front and back sides, and a maximum of two cakes in the pot at the same time, so how many minutes does it take to bake three cakes at most?

I thought about it and came to the conclusion: it takes 3 minutes: put the first one.

1. Put the second cake into the pot at the same time, after 1 minute, take out the second cake, put in the third cake, and turn the first cake over; Bake for another 1 minute, so that the first piece of bread is ready, take it out. Then put the reverse side of the second cake and turn the third cake over at the same time, so that it is all done in 3 minutes.

I told my mom about the idea, and she said that it wouldn't be that coincidental, there had to be some error, but the algorithm was correct. It seems that we must.

In order to better make mathematics serve our lives.

Mathematics should be learned in life. Some people say that the knowledge in books has little to do with reality. This says their.

The ability has not been fully exercised. It is precisely because of the inability to understand and apply it in daily life that many people do not pay attention to mathematics. I hope that the students will come to life.

Using mathematics in life, mathematics is inseparable from life, and if you learn deeply and thoroughly, you will naturally find that mathematics is actually very useful.
