Numbers

It was my friend’s 30th birthday on April, 3rd, and she is now 30 years old. Let’s talk about numbers! Numbers are used in many forms. The way they are said and written can change according to the context. There are even some idioms that use numbers!

One of the most commonly confused aspects of numbers is the difference between Cardinal and Ordinal numbers. Cardinal numbers are the typical counting numbers: 1, 2, 3. Ordinal numbers are used for orders in sets: 1st, 2nd, 3rd. They are used for dates: April 22nd, March 5th, January 3rd. Ordinal numbers are frequently seen when they are used for: birthdays, weddings, sporting events, and prizes.

Example: Our wedding anniversary is on March 5th.
Example: “First place goes to the Green Team.”

How do you talk about money?


$30 “Thirty dollars”
$9.99 “Nine dollars and ninety-nine cents” or the more informal and common “nine ninety-nine”
Incorrect: “Nine ninety-nine dollars”

Plurals


When making a number plural add “s”, “es”, or “ies.” Do not use apostrophes.

Correct: “In the 1800s, tens, sixes, twenties, thirties…”
Incorrect: “In the 1800” or “in the 1800’s.”

Commas:


In numerals with more than three digits, use a comma after every third digit from right to left. Do not include numbers right of the decimal point in your count.

Example: 98,375,242,156,256,644,451

While we are at it, let’s review:

10 - ten
100 - one hundred
1,000 - one thousand
10,000 - ten thousand
100,000 - one hundred thousand
1,000,000 - one million
10,000,000 - ten million
100,000,000 - one hundred million
1,000,000,000 - one billion

Hyphens


When they are written as words, whole numbers between twenty-one and ninety-nine are hyphenated.

Example: Forty-three people won the prize this year.


En-dashes


Use an en-dash to separate digits in a range.

Example: 1–15 “one to fifteen"

The Number Sign or Pound Sign #


Example: #5 “number five”

Example: 8:45 p.m.

(Did you know there is a way to say phone numbers in the US? It is usually “4-1-0, 7-0-6, 7-7, 2-5.” If you say it differently, it may confuse people. How do people say phone numbers in your country?)
