In many reference types, you must include the page numbers of the work, for example journal articles, newspaper articles, and contributions in edited books. Citation styles format page numbers in myriad ways. Here are a few examples: 357-389, 357-89, 357, 357ff., P. 357-389, pp. 357-389. The same applies for cited page numbers.
If necessary, enter prefixes and suffixes. The example shown would be used for the following formatting: p. 112 and pp. 357–389
