Let’s talk numbers. This is another topic that I file under the category of ‘things I always find myself having to correct when editing other people’s work’. (In case you’re wondering, two other topics in this category are the misuse of capitalsand double spacing between sentences.)
Let’s dive straight in, bearing in mind that there are few absolute rules on this topic and most of the following are really questions of style.
1. Digits or letters?
When using numbers in your writing, smaller whole numbers are generally spelt out (i.e. written as words) while larger numbers are written in digits. So ‘1’ is written as ‘one’; ‘100’ is written as 100.
