Writing-Handling Numbers

Sometimes when you write, you're going to need to include a mention of numbers of things. In formal writing, it's best to follow this simple rule: write the numbers from one (1) to ten (10) using letters; numbers eleven (11) and larger can be written using just the numbers.

Below are two examples illustrating this rule.

Terry bought nine types of soda for the party.
There were 45 people at the city council meeting.

Why does this rule for writing out the numbers using words only apply when going up to ten?

Well, first of all, those are sho rt, easy words to write (or type). Could you imagine having to write every number with wor ds? Gosh! It would be a pain to have to type one thousand five hundred twenty seven instead of 1,527. Secondly, remember that this is just for formal writing, such as essays. Other types of writing (informal emails, lists, or memos) can use numbers for any value.

Start to look for this when you read newspaper or magazine articles! I bet you'll begin to notice this more and more.

Give it a try. Write two sentences. The first one should use a number where the rule tells you to write it out using words. The second sentence should use a number that does not have to be written in words. Let's see how you do! I'll start!

I can run up to four miles. I hope to be able to run 13 miles one day!
