English Lesson: Numbers153

Numbers are an essential part of everyday life. We use them to count objects, tell time, measure distances, and much more. In English, there are two main types of numbers: cardinals and ordinals. Cardinals tell us how many of something there are, while ordinals tell us which number in a series something is.

Cardinals

The cardinal numbers in English are:

one
two
three
four
five
six
seven
eight
nine
ten

The numbers from eleven to nineteen are formed by adding the suffix "-teen" to the numbers one to nine. For example, eleven is ten plus one, so it is written as "eleven." The numbers from twenty to ninety-nine are formed by combining the tens place and the ones place. For example, thirty-five is written as "thirty-five." The numbers one hundred, one thousand, one million, and so on are written as one word.

Ordinals

The ordinal numbers in English are:

first
second
third
fourth
fifth
sixth
seventh
eighth
ninth
tenth

The ordinal numbers are used to tell us which number in a series something is. For example, the first person in a race is the winner, the second person is the runner-up, and so on. The ordinal numbers are also used to indicate dates. For example, the fourth of July is the fourth day of July.

Using Numbers

Numbers can be used in a variety of ways in English. Here are a few examples:
To count objects: We can use numbers to count objects, such as apples, oranges, or cars.
To tell time: We can use numbers to tell time, such as 10:00 AM or 3:30 PM.
To measure distances: We can use numbers to measure distances, such as 10 miles or 5 kilometers.
To indicate dates: We can use numbers to indicate dates, such as July 4th or December 25th.
To write numbers: We can use numbers to write numbers, such as 123 or 456.

Numbers are an important part of English. By understanding how to use numbers correctly, you can improve your communication skills and your ability to understand English texts.

Here are some additional tips for using numbers in English:
When writing numbers, it is important to use the correct punctuation. For example, we use a comma to separate the thousands place from the hundreds place, and a decimal point to separate the ones place from the tenths place.
When writing numbers in words, we use a hyphen to connect the tens place and the ones place. For example, we write "twenty-five" instead of "twenty five."
When writing numbers in a series, we use a comma to separate the numbers. For example, we write "1, 2, 3, 4, and 5" instead of "1 2 3 4 and 5."

By following these tips, you can improve your ability to use numbers correctly in English.
