do you use page numbers for in text in apa format
The most common and frequently used rule for writing numbers in APA style is determined by whether the number is under 10. All those numbers should be written out in word form, such as four or seven. A number 10 and above is written as a numeral, such as 10, 17, 233. One of the exceptions to this rule is when a sentence starts with a number. In this case, the number is always written out as a word.
