Five/five, four/four, one/one… how to read correctly in the sequence of natural numbers?

In mathematics, a natural number is a set of numbers from 0, 1, 2, 3, 4, 5, 6, 7, 8, 9…and denoted by N. The smallest natural number is 0. .

If the natural number stands alone, then you can write and read too simply. But when standing in the thousands, special units on the value-added invoices or with this sequence of numbers, how to read these natural numbers exactly. This is not only a concern of adults but also of primary school students.

Most of us do not understand the rules about reading and writing numbers, depending on the case, there are 2 ways of reading such as: 1 (one or one), 4 (four or four), 5 (five or five), so there is a question. questions and controversies about reading. This knowledge has been learned since elementary school, but because we have not really noticed these small things or because the knowledge has been too long, we get confused. In the article below, the Network Administrator will guide you how to pronounce the correct sequence of natural numbers. Invite your reference.

How to read natural numbers

To read natural numbers correctly, the first thing we need to do is split the sequence into classes, each class has 3 rows in order from left to right. When reading you combine reading numbers as well as class names.

For example:

537 797 686

Millions of units.

Read: Five hundred three seven million seven hundred nine seven thousand six hundred eight six.

So, if you want to read correctly, you must know how to read 3-digit numbers. Reading the correct number will correct the spelling mistake.

1. Where the number ends in 1

If the number ends in 1, we will have two basic readings: "fashion" and "one".

Case 1: 1 reads as “one” when tens is equal to or less than 1

For example:

501: five hundred and one

911: nine hundred eleven

67811: sixty seven thousand eight hundred eleven

Case 2: 1 reads as "fashion" when the tens digit is greater than or equal to 2, less than or equal to 9.

(read as "fashion" when combined with the word "ten" immediately before).

For example:

891: Eight hundred and ninety-one

689121: Six hundred and eighty-nine thousand one hundred and twenty-one

2. In case of numbers ending in 4

Case 1: We will say "four" when the last number of the tens series is less than or equal to 1.

For example:

6704: Six thousand seven hundred and four

89514: Eighty-nine thousand five hundred and fourteen.

Case 2 : Read as "four" when the tens digit is greater than or equal to 2 or less than or equal to 9.

(When reading "four" we should combine with "ten" immediately before in the sentence)

For example:

324: Three hundred twenty-four. (Three hundred and twenty-four)

1944: One thousand nine hundred forty-four. (One thousand nine hundred forty-four)

678934: Six hundred and seventy-eight thousand nine hundred thirty-four

(*Note: Can be read as “four” when the tens digit is equal to 2 or 4).

3. The case where the number ends with 5

Case 1 : Read as "five" when tens is zero or when combined with words indicating row names, the word "ten" follows.

For example:

78905: Seventy-eight thousand nine hundred and five

505155: Five hundred and five thousand one hundred and fifty-five.

Case 2 : When the number ends with 5 we will read it as "five" when the tens number is greater than 0 and less than or equal to 9

(pronounced “five” when combined with the preceding word “ten” or “ten”).

For example:

9845: Nine thousand eight hundred forty-five

5555: Five thousand five hundred and fifty-five

98675: Ninety-eight thousand six hundred and seventy-five

5.025,110: Five million, zero hundred and twenty-five thousand, one hundred and ten

555,555: Five hundred and fifty-five thousand, five hundred and fifty-five

505.515: Five hundred and five thousand, five hundred and fifteen
