1. ## 'Sum' Notation?

I looked throuh the latex forum, but I can't seem to get the latex to note this correctly:

n
$\sum$
r=1

Above, I typed the n above and the R=1 beneath, but in a question, the sum notation is in the middle of the question, so I don't have this option. :s.

Thanks in advance for any help.

Hi Quacky,

Try this: $\sum\limits_{r=1}^{n}$

Double click on the Sigma notation to see the Latex code used to generate it.

3. Thanks for the fast response.

4. You can also do it this way:

\displaystyle \sum_{r=1}^n

This yeilds: $\displaystyle \sum_{r=1}^n$
