The reading method is: the numbers should be capitalized, such as the numbers written in one, two, three, four, five, six, seven, eight and nine.

For example, 68 is pronounced as 68.

Writing means writing with lowercase Arabic numerals, such as the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9.

For example: 74, writing: 74. Second, the writing is different: "reading" is a capital number, "writing" is an Arabic number, that is, how to remember it. For example, the number 58 is pronounced 58. Writing: 58.

In math homework, reading is the number written and read in Chinese characters, and writing is the number to be read in Arabic numerals.
