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:

Millions of units.

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

Read natural numbers correctly

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
