    '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.

    You can also do it this way:

    \displaystyle \sum_{r=1}^n

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