When writing large numbers, the British use a comma as a separator every three digits. This is known as the comma-separated numbering system or a thousands separator. For example, instead of writing 1000000, the British would write it as 1,000,000.

This system is not unique to the British and is commonly used in countries with a European influence. However, it is not universal, as some countries use a dot as a separator or group numbers differently.

According to historian Bill Bryson, the use of the comma as a separator became prevalent in the sixteenth century and was fully established by the eighteenth century. Bryson notes that initially, it was not mandatory to use the thousands separator, and it was up to the writer’s preference.

Interesting facts on large numbers:

- The largest named number is googolplex, which is a one followed by a googol zeros.
- The term “googol” was coined by nine-year-old Milton Sirotta, who was the nephew of mathematician Edward Kasner.
- There is a mathematical concept known as Graham’s number, which is a number so large that its digits cannot be written down in the observable universe.
- In 2019, mathematician Timothy Browning made headlines for discovering a new record-breaking prime number with over 24 million digits.

A helpful table for understanding the comma-separated numbering system:

Number | Standard | British |

1000 | 1,000 | 1,000 |

10000 | 10,000 | 10,000 |

100000 | 100,000 | 100,000 |

In this video, Vanessa from SpeakEnglishWithVanessa.com explains how to say big numbers in English. There are many ways to say these numbers, depending on the situation. One common way to say a number is to say each individual number, such as “one hundred and twelve” or “two hundred and five.” When talking about specific situations, such as hotel rooms or phone numbers, you might say “one twelve” or “two hundred and five.” When counting items, you might say “one two five.” Vanessa also explains that you can use these same numbers in phone numbers and in other contexts, such as “I’m in room two hundred ten.”
