How to enrich your knowledge?

Mathematics is one of the compulsory subjects, so it is necessary to study mathematics seriously from the beginning of junior high school. So, how do you learn math well? Here are a few methods for reference:

1. Pay attention to listening and lectures in class, and review in time after class.

The acceptance of new knowledge and the cultivation of mathematical ability are mainly carried out in the classroom, so it is necessary to pay attention to the learning efficiency in the classroom and seek the correct learning method. During class, you should closely follow the teacher's ideas, actively think about the following steps, and compare your own problem-solving ideas with what the teacher said. In particular, it is necessary to grasp the learning of basic knowledge and basic skills, and review them in a timely manner after class without leaving any doubts.

First of all, it is necessary to recall the knowledge points taught by the teacher before doing various exercises, correctly grasp the reasoning process of various formulas, and try to recall as much as possible without using the act of turning the book immediately if it is not clear. Conscientiously and independently complete homework, diligent thinking, in a sense, should not cause a learning style that does not understand that is asked, for some topics due to their own unclear thinking, difficult to solve for a while, should let yourself calm down and seriously analyze the topic, try to solve it yourself. In each stage of learning, it is necessary to sort out and summarize the points, lines, and surfaces of knowledge to combine and weave them into a knowledge network and incorporate them into their own knowledge system.

2. Do more questions appropriately and develop good problem-solving habits.

If you want to learn mathematics well, it is inevitable to do more problems, and you must be familiar with the solution ideas of various types of questions. At the beginning, you should start with the basic questions, take the exercises in the textbook as the standard, practice repeatedly to lay a good foundation, and then find some extracurricular exercises to help you develop ideas, improve your analysis and solving skills, and master the general rules of problem solving. For some easy-to-make questions, you can prepare a set of mistakes, write out your own solution ideas and the correct solution process, and compare the two to find out your mistakes, so as to correct them in time.

In normal times, it is necessary to develop good problem-solving habits. Let your energy be highly concentrated, so that your brain is excited, your mind is quick, you can get into the best shape, and you can use it freely in exams. Practice has proven that:

When it comes to critical times, you will be in the same way as you would normally practice. If you are casual, careless, careless, etc., you are often fully exposed in the big exam, so it is very important to develop a good habit of solving problems in ordinary times.

3. Adjust your mentality and treat the exam correctly.

First of all, we should focus on the three aspects of basic knowledge, basic skills, and basic methods, because the vast majority of each exam is also a basic topic, and for those difficult and comprehensive topics as an adjustment, think carefully, try to figure yourself out, and summarize after completing the questions. Adjust your mentality, make yourself calm at all times, think in an orderly manner, and overcome impetuousness. In particular, I must have confidence in myself, always encourage myself, no one can knock me down except myself, I must have my own pride, and no one can break me.

Before the exam, you should be prepared, practice the regular questions, put your own ideas, and do not go to improve the speed of solving the questions on the premise of ensuring the accuracy before the exam. For some easy basic questions, you must have 12 points to get full marks; For some difficult problems, you should also try to get points, and learn to try to score in the exam, so that your level is normal or even extraordinary.

It's the age of the Internet, and it's important to make the most of the big library of resources on the Internet, as long as you don't play games all day like other game fans. That network is absolutely useful for you!

There are also magazines, newspapers, television, etc. As long as you have a heart, knowledge is everywhere!

Learn a lot

Look at a lot of books

There are benefits

In fact, the key to learning knowledge is to put new knowledge into the original knowledge network and link it with old knowledge. Therefore, it should be very common for knowledge to cross oranges and defeat. Here are some of the ones you came across in reading the book, and you can update them anytime you think about it later:

1.Risks and benefits are often directly proportional. a) Robert McGee "Stories":

Life teaches us that the scale of value of any human desire is directly proportional to the risk taken in pursuing it. b) Howard Marks, "The Most Important Thing About Investing": Higher investment risk leads to more uncertain outcomes.

The schematic diagram is as follows:2The value of uncertainty.

a) The Mindset of Economics: "Uncertainty: A Necessary Condition for Profit".

b）《what i wish i knew when i was 20》：“uncertainty is the essence of life, and it fuels opportunity.”3.

In reading, "asking questions-questions" can be very useful a) "How to Read a Book": "The core of active reading: you ask questions when you read - questions that you yourself must try to solve in the process of reading."

b) "Cognitive Psychology and Its Implications" mentions the "PQ4R method" of reading, where the "Q" refers to asking questions, and. Circular tremor 4Everything in the world is interconnecteda) The Economic Way of Thinking:

The economics way of thinking is that everything is interconnected. b) Social Psychology: "Our lives are connected by a myriad of invisible threads.

Herman Melville. c) The Meditations: "All things are interconnected, and this bond is sacred, and there is hardly anything that is not connected with anything else"5

The so-called "problems" in our daily lives, and the "conflicts" in the drama a) "Pyramid Principle": "Problem" refers to the fact that you don't like a certain outcome and want to get other outcomes The diagram is as follows: b) "Story":

between its subjective expectations and objective results. Digging a chasm" is as follows: 6

diminishing marginal returns a) This is a basic principle in economics and will not be repeated. b) Robert McCann, "Stories": "Stories must create this dynamic alternation between positive and negative emotions in order to conform to the 'diminishing return principle'.

The principle of diminishing returns is equally true in life and in stories: the more we experience something, the less effect it will have. ”

<> "Financial Knowledge: A Round, B Round, C Round, First Debate Angel Round."

It's not uncommon to see news like this.

Ofo completed the E2-1 round of financing, and the financing amount was as high as the announcement of a certain platform and obtained a B round of 100 million US dollars", "financing, the financing amount is 100 million yuan" So, what is the concept of ABCDE round financing? What's going on with the seed round and the angel round? What are the differences between them?

In fact, there is no strict definition of a funding round. To put it simply, it's divided like this:

1. Seed Round:

The project is only one concept, and it is financed by face-brushing.

2. Angel Investment (AI):

Angel investment is generally a start-up early project company has a preliminary appearance of the product (prototype), has a preliminary business model, has accumulated some core users (angel users), and even some do not have a complete product and business plan, at this time it is generally to find angel investors, angel investment institutions Angel investment is a kind of venture capital, and the amount of investment is generally small. The investment level is generally between 1 million RMB and 10 million RMB. The initial angel investors are referred to as 3F, namely Family, Friends, and Fools, and angel investors generally exit after Series A.

3. Series A financing.

The company's products have matured, began to operate normally for a period of time and have a complete and detailed business and profit model, and have a certain status and reputation in the industry. At this point, the company may still be in the red. The capital** is generally a professional venture capital institution (VC), and the investment volume is generally 10 million RMB to 100 million RMB.

4. Series B financing.

After a round of burning money, the company has achieved great development, and some companies have begun to make profits. There is no problem with the business model and profit model, and it is necessary to launch new businesses and expand new areas, so more capital flows are needed. Most of the funds** are the previous round of venture capital institutions followed by new venture capital institutions, private equity institutions (PE) joined, and the investment volume is more than 200 million RMB.

5. Series C financing.

The company has developed to a very mature stage, has begun to make profits, and is basically the top three in the industry, and it is not far from being listed. In addition to expanding new business, this round also has the intention of completing the closed loop of business and writing a good story to prepare for listing. The funds ** are mainly PE, and some of the previous V (will also choose to follow-up.

Investment level: more than 1 billion RMB, generally (after the round is listed, there are also companies that choose to finance the D round, but not many.)

6. The upgraded version of Series D, Series E, and Series F financing.

What I would like to share with you today is how to establish your own knowledge framework and improve your knowledge structure, which is actually a process of knowledge collation. The term "knowledge framework" was a term that we all heard when we were in school, when the teacher always asked each of us to build our own framework. But at that time, many people actually did not have a sense of framework, which would cause the things to learn to be unable to connect together.

When a topic examines multiple knowledge points, he will be confused, which is a manifestation of the lack of framework of knowledge. Now that we are careful to keep an eye on lead, we bring up the word again, and it is only more important than before. When building your own knowledge framework, there are two principles to follow:

The first principle, you must remember, no other people's framework is completely suitable for you, just like the method of self-use knowledge framework that I introduced to you today, I have explored and practiced it myself. In the process of exploration, I will combine some methods that others say, absorb them into my own, I will take some of the methods that are useful to me, and slowly eventually form a system of my own. So we can't completely use other people's methods of tidying up, just like we can't tidy up our own home according to what others say, everyone has him.

Books are. Knowledge is indeed the result of accumulation. However, from the current point of view, if you want to expand your knowledge and increase your knowledge, you must pay attention to these things first.

1. The purpose of reading. Reading is not for showing off, if it is for showing off, just remember a large number of famous sayings and famous names and famous books in ancient and modern China and foreign countries.

However, I think that the desire to expand myself must be based on improving my own quality. There is poetry and books in the belly, so reading is indeed the best choice.

2. The scope of reading. It should vary from person to person! I don't advocate that everyone's reading history is the same.

But no matter which line of work you do, you should "some" dabble in some books in this area: Chinese classical literature, Chinese modern and contemporary literature, literary theory, philosophy, aesthetics, Western poetry, popular science, depending on personal preferences and careers, choose the books that suit you. 3. How to read a book.
