## List of Numbers: Cardinal Numbers

Cardinal numbers are the numbers used to count and quantify things. They are the most basic type of numbers and are used to represent the quantity of objects, people, or things. Cardinal numbers are also called counting numbers because they are used to count the number of objects in a set.

Cardinal numbers are used in a variety of contexts, such as in math, science, and everyday life. For example, in math, cardinal numbers are used to represent the number of elements in a set, the number of sides in a polygon, or the number of terms in a sequence. In science, cardinal numbers are used to represent the number of atoms in a molecule, the number of cells in an organism, or the number of planets in a solar system. In everyday life, cardinal numbers are used to count money, measure quantities of ingredients in recipes, or keep track of time.

## List of Numbers: Ordinal Numbers

Ordinal numbers are a type of number that is used to describe the position or order of an object in a sequence. They are denoted by the symbol “O” and are used to indicate the rank or position of an object in relation to others in a set.

Ordinal numbers are used to indicate the position or rank of an object in a sequence. They are commonly used in sports to indicate the rank of a team or athlete, and in academic settings to indicate the rank of a student in a class. Ordinal numbers are also used in everyday language to describe the order of events, such as “first come, first served” or “second to none.”

Here are some examples of ordinal numbers in a table:

## List of Numbers: Decimal Numbers

Decimal numbers are a system of numbers used to represent non-whole numbers or fractions. They are also known as base-10 numbers, as they are based on the number 10. Decimal numbers are represented using a decimal point and digits to the right of the decimal point that represent the fractional part of the number. For example, the number 3.14 is a decimal number, with 3 being the whole part and 0.14 being the fractional part.

Decimal numbers are used in a variety of contexts, such as in math, science, and everyday life. For example, in math, decimal numbers are used to represent fractions, percentages, and ratios. In science, decimal numbers are used to represent measurements of length, weight, and volume. In everyday life, decimal numbers are used to represent prices, interest rates, and exchange rates.

Here are some examples of decimal numbers in use:

• The price of the item is \$3.99.
• The temperature is 23.5 degrees Celsius.
• The interest rate is 5.25%.
• The weight of the object is 0.75 kilograms.
• The length of the room is 4.5 meters.

In each of these examples, the decimal number is used to represent a quantity that is not a whole number. Decimal numbers are essential for representing non-whole numbers and fractions, and they allow for more precise measurements and calculations.

## Writing Numbers

When it comes to writing numbers, there are two main ways to do it: in words or in numerals. In this section, we will cover both methods and provide examples to help you understand how to write numbers correctly.

### Writing Numbers in Words

Writing numbers in words is often used in formal writing, such as academic papers or business reports. Here are some rules to follow when writing numbers in words:

• Spell out numbers one to nine and use numerals for numbers 10 and above.
• Use hyphens for numbers between 21 and 99 (e.g., twenty-one, forty-five).
• Use “and” to denote the decimal point (e.g., two hundred and fifty-five point five).

Here are some examples of how to write numbers in words:

• 3 (three)
• 12 (twelve)
• 45 (forty-five)
• 127 (one hundred and twenty-seven)
• 3.14 (three point one four)

### Writing Numbers in Numerals

Writing numbers in numerals is more commonly used in everyday writing, such as emails or text messages. Here are some rules to follow when writing numbers in numerals:

• Use numerals for all numbers, regardless of their value.
• Use commas to separate thousands, millions, etc. (e.g., 1,000,000).

Here are some examples of how to write numbers in numerals:

• 3
• 12
• 45
• 127
• 3.14

It is important to note that different countries have different conventions for writing numbers. For example, in some countries, the decimal point is denoted by a comma instead of a period. Make sure to check the conventions in your country before writing numbers.

In conclusion, writing numbers correctly is important in both formal and informal writing. By following these rules, you can ensure that your writing is clear and easy to understand.

## Conclusion

• Numbers are used in many different contexts, from telling time to giving directions.
• There are different types of numbers, including cardinal numbers, ordinal numbers, decimal numbers, and more
• Learning numbers vocabulary can help you in both speaking and writing English.
