Numbers and Symbols in English

by | Oct 5, 2026 | English Vocabulary | 0 comments

Numbers and symbols are an important part of everyday English. We use numbers to talk about age, time, dates, prices, measurements, quantities, and many other things. Symbols also appear everywhere—from mathematical calculations and percentages to money, temperatures, email addresses, and written communication.

Learning numbers and symbols in English involves more than simply recognizing them. You also need to know their names, meanings, and how to read them correctly. For example, 25% is read as twenty-five percent, $50 as fifty dollars, and 5 + 3 = 8 as five plus three equals eight.

In this guide, you will learn common numbers and symbols used in English and see practical examples of how they are read and used together. You will also find links to detailed lessons on number types, ordinal numbers, writing numbers, and mathematical symbols when you want to explore a topic in greater detail.

Numbers are used to represent quantities, amounts, positions, measurements, dates, time, prices, and other numerical information. In English, numbers can be written as numerals, such as 5, 20, and 100, or as words, such as five, twenty, and one hundred.

Symbols are special signs or characters that represent particular meanings, operations, units, or ideas. For example, the plus sign (+) represents addition, the percent sign (%) represents a percentage, and the dollar sign ($) represents dollars or a monetary value.

Numbers and symbols often appear together in everyday English. For example:

  • 50% — fifty percent

  • $25 — twenty-five dollars

  • 10°C — ten degrees Celsius

  • 3 + 2 = 5 — three plus two equals five

  • 1/2 — one-half

Knowing how to recognize, name, and read these combinations can help you understand English in everyday conversations, schoolwork, shopping, measurements, and written communication.

Numbers in English

Numbers are used in English to express quantity, order, age, time, dates, prices, measurements, and calculations. They can be written as numerals, such as 8, 25, and 100, or as words, such as eight, twenty-five, and one hundred.

Some common ways numbers are used include:

  • Quantity: I bought three books.

  • Age: She is 25 years old.

  • Time: The meeting starts at 9:30.

  • Date: The event is on October 15.

  • Price: The book costs $20.

  • Measurement: The table is 2 meters long.

  • Percentage: About 75% of the class passed.

English also uses different types of numbers for different purposes. Cardinal numbers such as one, two, and three show quantity, while ordinal numbers such as first, second, and third show position or order.

For a detailed explanation of number types, rules, and examples, see Numbers in English: A Complete Guide with Examples.

How to Read Numbers in English

Reading numbers correctly in English depends on how the number is being used. A number may represent a quantity, price, year, decimal, fraction, percentage, time, or measurement, and each type may be read differently.

Here are some common examples:

Written Form Read in English
15 fifteen
125 one hundred twenty-five
2026 two thousand twenty-six
3.5 three point five
50% fifty percent
$75 seventy-five dollars
1/2 one-half
8:30 eight thirty
20°C twenty degrees Celsius

Context is especially important. For example, 2026 may be read as two thousand twenty-six when referring to a year, while a decimal such as 2.5 is read as two point five.

Learning these patterns makes it easier to understand numbers in conversations, prices, dates, measurements, and other everyday situations.

For more detailed rules and examples, see How to Read Numbers in English.

Cardinal and Ordinal Numbers

Two common types of numbers in English are cardinal numbers and ordinal numbers. They serve different purposes when we talk about quantity and position.

Cardinal Numbers

Cardinal numbers tell us how many people, objects, or things there are. Examples include one, two, three, ten, and one hundred.

  • I have three books.

  • There are twenty students in the class.

  • She bought two tickets.

  • The building has ten floors.

Ordinal Numbers

Ordinal numbers show position, order, or rank in a sequence. Examples include first, second, third, fourth, and tenth.

Cardinal Number Ordinal Number
one (1) first (1st)
two (2) second (2nd)
three (3) third (3rd)
four (4) fourth (4th)
five (5) fifth (5th)
ten (10) tenth (10th)

For example:

  • Sara finished first in the race.

  • This is my second visit.

  • He lives on the fifth floor.

In simple terms, cardinal numbers tell us how many, while ordinal numbers tell us the position or order.

Common Symbols in English

Symbols are special characters used to represent operations, values, measurements, currencies, percentages, and other information. Some symbols are mainly used in mathematics, while others appear frequently in everyday English.

Here are some common symbols and their names:

Symbol Name Example
+ plus sign 5 + 2
− minus sign 10 − 3
× multiplication sign 4 × 5
÷ division sign 20 ÷ 4
= equals sign 2 + 3 = 5
% percent sign 50%
$ dollar sign $25
£ pound sign £20
€ euro sign €30
° degree symbol 25°C
# number sign / hash #5
& ampersand research & development
@ at sign name@example.com
/ slash and/or
* asterisk *See note below

The name and meaning of a symbol can depend on its context. For example, # may be called the number sign when used before a number, as in #5, or a hashtag when used on social media.

Mathematical symbols form a larger group with their own names and functions. For a more detailed list, see Basic and Important Math Symbols in English.

How to Read Numbers and Symbols Together

Numbers and symbols frequently appear together in prices, percentages, measurements, temperatures, calculations, fractions, and other everyday information. When reading them aloud, the symbol is usually expressed by its English name or by the word normally associated with it.

Here are some common examples:

Written Form Read in English
$50 fifty dollars
£25 twenty-five pounds
€100 one hundred euros
75% seventy-five percent
20°C twenty degrees Celsius
68°F sixty-eight degrees Fahrenheit
3.5 three point five
1/2 one-half
3/4 three-quarters
5 + 3 = 8 five plus three equals eight
10 − 4 = 6 ten minus four equals six
6 × 2 = 12 six times two equals twelve
20 ÷ 4 = 5 twenty divided by four equals five

Reading Currency

Currency symbols generally appear before the number in writing, but the currency name is spoken after the number.

  • $25 → twenty-five dollars

  • £50 → fifty pounds

  • €30 → thirty euros

Reading Percentages

The percent sign (%) is read as percent after the number.

  • 10% → ten percent

  • 50% → fifty percent

  • 99.5% → ninety-nine point five percent

Reading Temperatures

The degree symbol (°) is read as degrees when talking about temperature.

  • 15°C → fifteen degrees Celsius

  • 70°F → seventy degrees Fahrenheit

Reading Mathematical Expressions

In mathematical expressions, each symbol is read according to the operation it represents.

  • 7 + 2 = 9 → seven plus two equals nine

  • 8 − 3 = 5 → eight minus three equals five

  • 5 × 4 = 20 → five times four equals twenty

  • 12 ÷ 3 = 4 → twelve divided by three equals four

Learning to read numbers and symbols together is especially useful because these combinations appear frequently in everyday English, from shopping and weather reports to schoolwork and measurements.

Writing Numbers in English

Numbers can be written as words or numerals, depending on the context and style of writing. For example, the number 8 can also be written as eight, while 25 can be written as twenty-five.

Here are a few basic examples:

Numeral Written in Words
5 five
12 twelve
25 twenty-five
100 one hundred
250 two hundred fifty
1,000 one thousand

In general writing, smaller numbers are often spelled out, while numerals are commonly used for larger numbers, measurements, statistics, dates, times, prices, and percentages. The exact choice can also depend on the writing style being followed.

For example:

  • She bought three books.

  • The bag costs $45.

  • The class starts at 9:00 a.m.

  • Sales increased by 15%.

  • The journey is 120 miles long.

Numbers may also require special writing conventions when they appear at the beginning of a sentence or when they are used for dates, decimals, fractions, and ordinal positions.
