1, with different meanings: it is pronounced as a capital number in the writing process, such as capital one, two, three, etc. Writing is the process of writing, using lowercase Arabic numerals, such as lowercase 1, 2, 3 and so on.
2, the writing is different: reading and writing is "capital figures"; Write in lowercase (Arabic numerals).
3, the concept is different: read: numbers should be capitalized, such as numbers capitalized one, two, three, four, five, six, seven, eight, nine. Writing means writing with lowercase Arabic numerals, such as the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9.
Knowledge expansion
In mathematics, reading and writing are two different concepts, and there are obvious differences in representing numerical values.
First of all, reading refers to using Chinese capital figures to represent numbers. For example, the number "12345" is read as "12345".
This representation method is often used in financial, statistical and other occasions that need to express the amount in words to ensure the accuracy of the amount and avoid being tampered with. In reading, each number has a fixed pronunciation, such as "1" is "one", "2" is "two", and so on.
On the other hand, writing refers to using Arabic numerals to represent numbers. For example, the number 12345 is written as 12345. This representation is common, because Arabic numerals are easy to understand and easy to calculate and write.
In writing, we usually use 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and uppercase and lowercase letters to represent more complex numerical values.
In addition to reading and writing, there are concepts such as carry system and numbers in mathematics. The carry system refers to a numerical representation in which the weight of each bit depends on its position.
For example, the weight of each digit in the decimal system is a power of 10, for example, the single digit is 10 0 = 1 010, and the hundred digit is102. A number refers to a number in a number, such as single digit, ten digit, hundred digit, etc.
In practical application, reading and writing often need to be converted according to specific occasions and needs. For example, in financial reports, amounts need to be expressed in capital letters, while in spreadsheets, Arabic numerals need to be used.
Correctly understanding and using the concepts of reading and writing, as well as the carry system and digits, is of great significance for accurately representing numerical values, carrying out mathematical calculations and solving various problems.
To sum up, reading and writing are two different ways to represent numerical values in mathematics. Pronunciation uses capital numerals to represent numerical values, and writing uses Arabic numerals to represent numerical values. In the specific application, it is necessary to choose the appropriate representation according to the needs. Correctly understanding and using these concepts is of great significance to mathematics learning and practical application.
