# \cdots and \dots, which one to use?

Sometimes I just don't know which one to use, \cdots or \dots? This question is more like using the correct math style instead of technical details of LaTeX, but I hope someone can help.

• For maths, I use \dots, and amsmath is smart enough to know which king of dots it has to use For text, I have the unicode character … on my keyboard. – Bernard Aug 8 '17 at 13:47

If you have to decide, decide between \ldots and \cdots which are the latex commands for low and centred dots, \dots is an amsmath command that tries to automatically make the choice for you and automatically switches between \ldots and \cdots depending on the following symbol.
As a general rule, use \cdots if the following thing is centered on the math axis, such as + or \rightarrow, and \ldots if it is punctuation such as . or ,
