Composition 1. Title: Correct and standard usage of numbers

In modern society, numbers are everywhere. We can record time, statistics and make various calculations through numbers. However, because many people have some mistakes or irregular problems when using numbers, communication and understanding are troubled. Therefore, the correct and standardized use of numbers has become an important problem that we must face and solve.

First of all, we should make clear the angle and choose the law of mathematical writing as the idea of our article. Mathematical writing rules are a strict standard, which can ensure the clear transmission and correct understanding between numbers and should be widely used in daily life. By following these rules, we can avoid misunderstanding and confusion caused by irregular digital writing.

First, the writing specification of integers

In order to keep the standard writing of integers, we need to pay attention to the following points:

1. No need to add the "+"before zero;

2. When writing large integers, use a set of three digits (in thousands) separated by commas. For example, "1 ,000,000" is one million.

3. When writing a negative integer, the negative sign "-"should be close to the number, for example, "-5".

Second, the writing standard of decimals

Decimals are also widely used in daily life. In order to keep the decimal number written correctly, we need to pay attention to the following points:

1. The decimal point "."should occupy a whole word position, and should not stick to numbers;

2. When the decimal part is zero, the zero after the decimal point can be omitted, for example, "3.0" can be abbreviated as "3";

3. When there are too many decimal places, ellipsis or scientific notation should be used. For example, 0.00000 1 can be written as 1e-6.

Third, the percentage of writing norms.

As a common data expression, percentage writing also has fixed rules:

There is no space before 1. percentage, for example, "45%" means 45%;

2. When the percentage is small, you can write a percentage sign next to the number, such as "0.5%";

3. Large percentages can be separated by commas, which is convenient for reading and understanding the proportional relationship.

Fourth, the writing standard of date and time.

In order to avoid the ambiguity caused by the standard of date and time writing in communication, we need to pay attention to the following points:

1. Dates are generally written in the order of "year-month-day", such as "2022 1 1 10/day";

2. Time is generally written in the order of "hours: minutes: seconds", such as "15:30:45".

To sum up, using numbers is an inevitable part of daily life and work. Writing numbers correctly and regularly can express yourself more accurately and avoid misunderstanding and confusion caused by irregular writing. Therefore, we should always follow the law of mathematical writing and use numbers reasonably to improve the efficiency of communication and understanding.

2. Title: Writing and Standard Usage of Numbers

Numbers are an indispensable part of our daily life. Writing numbers accurately and standardly is the basic requirement of expressing information and the performance of respecting readers. In all kinds of documents, manuscripts and scientific reports, the correct use of numbers is also an important aspect of professional quality. This paper will discuss the standard use of numbers from the writing idea of numbers.

First, write integers correctly. When expressing integer concepts such as age, time and quantity, Arabic numerals should be used and written according to the writing habits of national standards. For example, we use "23 years old", "30 minutes" and "4 apples" instead of "23 years old", "30 minutes" and "4 apples". At the same time, when expressing the year, we should also pay attention to the Gregorian calendar and use Arabic numerals, such as "2023" and "1990" instead of "2023" and "1990".

Secondly, the writing of decimals should also follow the norms. Decimals are used to represent numerical values with higher precision, which is very important for scientific experiments, statistical data and other fields. When writing decimals, we should use the decimal point "."to completely express the integer part and the decimal part. Such as "3. 14" and "0.5" instead of "3. 14" and "one fifth". In addition, for decimals less than 1, add "0" before the decimal point, such as "0.25" instead of ".25".

In addition, the percentage of writing also needs to follow certain norms. Usually, when expressing percentage, we use the percent sign "%"to clearly distinguish the percentage from the original value. For example, "25%" means 25% instead of "25/ 100" or "0.25".

Under special circumstances, some numbers may be written differently. For example, in conventional usage, the expression of digital quantity can take different forms, such as Chinese characters, pinyin or English. However, in formal documents and occasions, we should still insist on writing with Arabic numerals to avoid misunderstanding.

In a word, writing numbers accurately and standardly is the basic requirement for effectively transmitting information, and it is also an important embodiment of showing professional quality. In our daily life and various documents, we should always use Arabic numerals and compile them according to the habits of national standards. For different types of numbers, such as integers, decimals, percentages, etc., we should master their writing norms and express them in strict accordance with the requirements. Only in this way can digital information be transmitted correctly and standardized, ambiguity and misunderstanding can be avoided, and the professionalism and readability of the manuscript can be improved.

3. Title: Correct and standard usage of numbers

Every day, we are exposed to all kinds of figures, whether it is the amount of shopping in life, the exam results in study, or the statistical data at work. The correct use of numbers can not only improve the standardization of writing, but also accurately convey information and avoid misunderstandings and troubles caused by digital errors.

First of all, we should pay attention to the writing norms of numbers. When writing numbers, we should maintain a certain consistency, that is, use Arabic numerals (0-9) instead of Chinese characters to write. For example, we should use "9" to represent nine, not "9" in Chinese characters. This can make readers understand the size and meaning of numbers more intuitively, save space and increase the conciseness of chapters.

Secondly, we should follow the standard pronunciation and pronunciation of numbers. For integers, we usually read numbers in Mandarin. For example, 123 is pronounced as "123" and 100 1 is pronounced as "100 1". For decimals, fractions and percentages, we should also follow the corresponding reading rules. For example, 0.5 is pronounced as "0.5", 2/3 as "3/2" and 30% as "30%". Following the correct number reading method is conducive to accurately conveying information and avoiding ambiguity.

In addition, pay attention to the collocation of numbers and units. When expressing specific numerical values, you need to add corresponding units in addition to writing the correct numbers. For example, when describing the distance, use "10 meter" instead of just writing the number "10"; When describing time, you should write "3 hours", not just the number "3". The reasonable combination of numbers and units can help readers better grasp the whole picture of information and effectively avoid misunderstandings.

Finally, pay attention to the format specification of numbers. In written expression, numbers are usually presented in different formats, such as Roman numerals and Arabic numerals. We need to choose the appropriate number format according to the specific situation and requirements and keep it consistent. For example, in literary works, we can use Roman numerals to represent chapter numbers, while in scientific papers, Arabic numerals are more suitable for data statistics. Choosing the correct number format is helpful to improve the overall quality and readability of the article.

To sum up, the correct and standardized use of numbers is the basis for improving the writing effect and the accuracy of expression. Attention should be paid to writing norms, pronunciation and reading methods, collocation units and selection of appropriate number formats. By following these principles, we can better convey information, express opinions and improve the quality and readability of articles. Only under the premise of correctly regulating the use of numbers can we convey our meaning to readers more accurately and communicate effectively.
