1, numbers within four digits, read from the high places in numerical order.
2. Numbers with more than four digits should be graded according to four digits from right to left, and then read from the highest level to one billion, ten thousand and one level in turn. Read the numbers in each level and their level names. The number in the billion-level is read according to the reading method of the single-level median, and then the word "billion" is added at the back; The numbers in the 10,000-level should be read according to the reading method of the first-level median, and then the word "10,000" should be added at the back.
3. No matter how many zeros are at the end of each level, don't read them; There is a "0" or several "0" on other numbers, all of which are read-only zeros.

The benefits of learning mathematics
People who are good at math are relatively smart and savvy, and they can show their advantages in dealing with people. The faster you think, the more ways and ideas you have. Cambridge, majoring in financial mathematics at Carnegie Mellon University in the United States, said that studying mathematics has brought her mental exercise and made me pay more attention to the rigor of thinking in my life.
For example, before solving a problem, I like to divide it into several sections, and each section is divided into several steps, so that I can dig slowly like a branch instead of thinking in confusion in front of a pile of data. Mathematics is the foundation of other disciplines, and it is easier for people who learn mathematics well to get into other disciplines. Learning software, computer, finance and other engineering majors is even more handy.
Can manage money better than others. The application of mathematics in life is everywhere. Nowadays, the society is already an information society, and mathematical knowledge is used in financial management and computers. Warren Buffett is very powerful, but Buffett's power is also based on mathematics. Buffett's decision-making process is actually the method of using subjective probability.
