At what point in your life did you find it useful to study math?

When shopping is on sale, especially when buying on Jingdong**, there are often activities full 199 minus 100, full 90 minus 50, but these participating goods have been mentioned in advance**, and if you are not careful, you may lose more than you usually buy, and at this time, mathematics needs to come in handy.

Maybe the whole mathematics and the whole mathematical formula is a miracle that happened in China in the Internet age, the whole mathematical formula is different from any mathematical formula in the past is that the whole mathematical formula is also the overall cosmology law, the universe may come from the vacuum quantum fluctuations, the so-called observable universe outside is the vacuum, the vacuum and the observable universe are one, can inspire people's understanding of the life of the universe, for example: according to the law of integral cosmology, it is found that the fifth force is the overall dynamic equilibrium force of the universe!

When I was teaching my elementary school cousin the Olympiad. When my cousin asked me about math problems, I looked at them with a confused expression, and I didn't even know how to do elementary school problems. It seems that learning mathematics well is still quite useful, and you can't underestimate the Primary School Olympiad!

When I was a sales manager, I was dealing with all kinds of data every day, haggling with customers, calculating freight rates with logistics companies, and fighting for commissions with bosses.

When you go to the supermarket to buy groceries, you have to calculate your salary at the end of the month. It doesn't seem to be of much use other than money.

Always go to a small shop to buy things, one day his son is doing his homework by the way to see the store, buy something to ask him to settle the bill, and finally calculate for a long time and find the wrong money, I told him for a long time how to add or subtract this money, at that moment I feel that mathematics is not good, this store may collapse.

Double 11, 400 minus 30, 200 get a 20 yuan coupon, 50 yuan deposit can be reduced 99 yuan ......So, how much will I get in the end? Good at math, let's do the math?

When I was shopping for vegetables, my aunt said that cucumbers were five pounds a piece, I said it was cheaper, she said that it was five dollars and three pounds, but fortunately, I learned mathematics and reacted quickly, or I would have gone in.

It's a small note.

Above: r=a(1-sinx).

If you hadn't heard a teacher talk about the Cartesian heart curve in high school, you might not have understood this love letter in seconds.

When I go to the supermarket, I always compare the same things with different brand manufacturers, especially when I count grams or catties, and I really regret not listening to the math teacher's class.

Jingdong buys things, 199-100, if you buy more than 199, it is not very cost-effective. So I tried my best to make it up every time, and I would never let him take advantage of my one yuan.

When solving equations in physics.

It's all nonsense, but of course it's useful for exams!

Bargain when you go to the market to buy groceries.

It is especially useful to improve children's academic performance, and will make children learn mathematics very well, which has a great role in daily life.

Of course, it is useful, mathematics is also needed in life, mathematics is needed in all aspects of life, and mathematics is everywhere in life.

Mathematics is the mother of all disciplines, and the development of mathematics has promoted the progress of other disciplines, without which modern technology would not have been possible.

Let's say I imagine a scenario that happens almost every day: you ride your bike to school this morning, drop by to buy breakfast, and then you bump into a classmate and walk with him to school, and because you walk slowly, you accidentally arrive late. The math in this life scenario is:

1. When riding a bicycle, have you ever thought about how many meters you walked on a pedal bike? We can measure the radius of the wheel and find it using the formula for the circumference of the circle. Or use a rope to lay on the ground and measure, or you have another way.

2. Then you see that the classmate next to you rides a bicycle faster than you, have you ever wondered how you judge who is faster and who is slower? Compare distances at the same speed? Or the same distance compared to speed? Absolutely.

3. When you go to buy breakfast, you find that the price of the bread you eat every day has increased, and you don't have enough money today, and you are very embarrassed. But have you ever wondered why the price has gone up? It turned out that the boss had carefully calculated that the price of this bread would be a few dollars to get the highest profit. Here's an example:

The owner of the bakery has been running the bakery for three months and found that the cost price of a certain bread is 2 yuan, the price is 5 yuan, and 100 pieces can be sold every day. We can solve it as a quadratic function.

If the price is increased by x yuan, the profit of each loaf is 5+x-2, and 100-5x pieces can be sold every day. According to: total profit = profit per loaf of bread number sold, columnist function:

y=（3+x）（100-5x）；Then use the vertex formula to find out when x is the most, the profit is the largest.

4. Do you know where you spent the most time on today's school journey? Draw a plane Cartesian coordinate system, the abscissa is the time, and the ordinate is the distance from home, and you can see it at a glance.

5. When you are late, you need to register with the staff on duty and ask to write down the name of the grade class. This way the school will know which class has the most tardiness and which class has the least tardiness this week. It's also a simple statistical question.

I'm just stating a very common thing, and mathematics is in our field of vision all the time. Circumference of a circle, distance formula, quadratic function, equation, planar Cartesian coordinate system, statistics, etc.

As we grow up, we already know that mathematics is helpful to our lives, but we always hate mathematics when we study, we feel that mathematics is so complicated, what is the future of life, and what needs to be recommended by him. The hot question is, in your opinion, how can learning math well help you in the future? I am a person who has come from the past, and in my opinion, learning mathematics well will help you in your future life, so I think there are several main aspects, and the following are my views and opinions, I hope it can bring some help and benefits to you.

First of all, mathematics is a necessary skill in our life, think when we buy vegetables, buy things, earn wages and so on need to calculate, every calculation is interconnected with our mathematical information, and it is inseparable from the knowledge of mathematics, so learning mathematics is very important for future life, as long as we learn mathematics? In my opinion, first of all, we should learn according to the most basic, and we can't make a mistake when it comes to our addition and subtraction, because our future life plus and minus maturity will carry us for the longest time, and it will also be good for our life. Therefore, for the arithmetic problems of addition, subtraction, multiplication and division, even if the graph is not wrong, because it is very closely related to our lives and helps us very much, so it is very important to learn mathematics well.

The second is that mathematics is a choice in our lives that can help us solve a lot of problems. For the problem of numbers, we don't have to have too much entanglement, for mathematics, we have more choices and challenges, there is no need to be confused there, and there is no need to hang there, so learning mathematics well is very useful for future life. Learning math well will help us a lot in calculating our salary in the future.

Therefore, we should take it seriously from the most basic learning, involving all aspects of life, and should not feel that we should give up when we start mathematics, and we should have a good attitude to learn mathematics.

It is crucial that learning mathematics is good for life and will also help us in our future lives. So also in my opinion, we should ask for help from the people around us. When we encounter a problem that we can't do, we should try to understand it, and we shouldn't pretend to understand it.

When you encounter some difficult exercises, you also need to ask the teacher and the people around you for help, answer questions, solve problems, and come up with the correct answer in the end.

When learning mathematics, you need to have a certain logical thinking, have a strong interest in mathematics, correct your attitude towards learning, have the spirit of perseverance, and ask teachers and classmates for some formulas and principles in time when you encounter problems that you don't understand.

Learning mathematics is very inseparable from life, so according to the needs of some hearts, as well as the lack of education and teaching planning, it is necessary to synchronize with the textbooks when learning, and to do more questions and practice. Judgment.

Mathematics is still relatively important in our lives, so we usually have to learn mathematics well, and ask questions if we don't understand something.

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

2. Investment and financial management. Calculation of interest, **, insurance, etc.

3. Area calculation. Housing, land occupation, farming, flowers, etc.

4. Calculation of volume and volume. Furniture, cars, house space, and much more.

5. Salary and expenditure management.

Go to the supermarket to check out, go back and forth, buy things, sell things.

Isn't it just simple operations such as addition, subtraction, multiplication, and division.

The way you think about everything you do uses all the ways of thinking in mathematics.

The law of division is used in architecture.

That's a lot! Save money, discounts and private money.

Mathematics is everywhere. In life, mathematics is used in many places. Mathematics has brought many conveniences to people's lives:

1. The meals that children eat every day are bought by their mothers from the market, and mathematics will be used at this time. For example, "How many pounds?" "How many?

A few kilograms? "It's all mathematically calculated. At the same time, the amount of food the child must also be calculated with mathematics, and the mother can make the child neither hungry nor wasted.

2. In school, teachers should distribute stationery to students very evenly, and mathematics should also be used at this time. Somewhere to Play: How Long Is It? How long does it take? And so on, all of them use mathematics.

3. Aunt Wang wants to plant vegetables on a fence against the wall in the yard, how to fence the most economical fence? How many fences do you need? Mathematics is also used here. Otherwise, there will be either more or less fences to prepare.

4. I went to eat pizza with my friends and ordered a 12-inch one, but after a while, the waiter came and said, "I'm sorry I can't make 12 inches now, can I change it to two 6-inch ones, the same." The friend listened and slapped the table:

Can it be the same? The formula for the area of a circle is r squared, and four 6 inches are equal to one 12 inches". Use the math to calculate whether the size of the pizza is a loss.

5. When the children tidy up the toys, how many kinds of points are there? When eating with the family, count the number of plates, bowls; count the number of fruits on the shelves when you go to the supermarket; Count the number of steps when going up the stairs; Counting the number of points or flowers, measuring the number of steps you take between home and the supermarket, etc., all use mathematics.

Time to buy something, cook and stir-fry.
