## Introduction

When you are writing an academic paper or essay, there is a very high probability that you would need to use numbers in your text. For example, having to report numerical information about the demographics of participants or the results of the statistical analysis carried out in the course of the research.

Furthermore, writing a non-empirical paper might also attract numbers as you may need to display the percentage of a population that is having the issues you are looking into and so on. Hence, it is essential to have guidelines for the use of numbers in academic papers. Plus, authors must be ready to follow the guidelines to ensure the readability of their paper.

Like most writing styles, APA style has guidelines for the use of numbers. Plus, it recommends that words should be used to express numbers that are below ten and using numerals to express numbers that are ten and above. This is the golden rule of the use of numbers in APA format. However, there are some exceptions to this rule, and these exceptions are what we would be looking at in this article.
