I have to type the product of n variables, `$x_1\cdot\ldots\cdot x_n$`

.

Although maybe this is semantically the right way (like it is for the sum), it doesn't look very well. What should be, typographically, a better way to do it?

For example:

Just the ldots as in `$x_1\ldots x_n$`

is confusing when there are going to be also lists of the variables separated by commas in nearby sentences.

With `\dotsc`

like in `$x_1\dotsc x_n$`

maybe, but is there a better idea?

## Best Answer

Use

`\cdots`

. (See also:`\vdots`

and`\ddots`

.)## Edit

Actually, I just read in the «Short Math Guide for LaTeX» by the AMS that:

`\dotsc`

is for dots with commas,`\dotsb`

is for dots with binary operators,`\dotsm`

is for multiplication dots,`\dotsi`

is for dots with integrals,`\dotso`

is for other dots.So,

`\cdots`

and`\ldots`

are commonly used but the AMS convention is to use the more semantic commands.
