The term “n dash” is a misspelling of en dash, which is the dash that is used in number ranges (e.g., “pp. 207–221”), among other uses.
The en dash is longer than a hyphen (-) but shorter than an em dash (—).

To type an em dash (—) on a Mac computer, hold down option + shift and press the hyphen key (to the right of the 0).
Alternatively, for many programs and applications, you can type an em dash by typing two or three hyphens (-) in a row. The program will automatically convert this to an em dash.
In Microsoft Word, there are several ways to type an em dash (—):
An en dash (–) is shorter and is used to indicate number ranges (e.g., “1958–1985”) or as a substitute for the word “to” in phrases like “the Albuquerque–Los Angeles flight.”
An em dash (—) is longer and is used like parentheses or commas to set off extra information or like a colon or semicolon to indicate a break in a sentence. For example: “My brother—well, technically my half-brother—is coming to visit this weekend.”
In British English, en dashes are used like em dashes. In this case, they have a space on either side. For example: “My brother – well, technically my half-brother – is coming to visit this weekend.”

Typically, there is no space around an em dash (e.g., “The flight—which had already been delayed three times—was canceled”).
One notable exception is that Associated Press (AP) style requires spaces around an em dash, so you may see this in news articles (e.g., “The flight — which had already been delayed three times — was canceled”).
Consult your style guide to see what is preferred. All of the major academic style guides (APA, MLA, and Chicago) recommend not putting spaces around em dashes.

| number | There are twenty-five students in my class |
