Hello and welcome to Wikipedia.

Your editing of factorial prompts some tips: Notice the difference between these two TeX displays:

- <math>\sum_{k=1}^n \log k!</math>

- <math>\sum_{k=1}^n log k!</math>

The first is standard. Similarly one writes \sin, \lim \max, \inf, \exp, \det, etc., with a preceeding backslash. This prevents them from being italicized as if they were variables and also makes sure a proper amount of space appears between this operator and the variable that follows it. In sup cases, such as \lim, and \int, it allows subscripts to appear directly below the operator, thus:

- <math>\lim_{\Delta x\to 0}</math>

- <math>\sup_{t\in\mathbf{R}} f(t) </math>

Although "displayed" TeX like the above looks good, on many browsers TeX embedded in lines of text looks misaligned and ugly. Thus I wrote log *n*! instead of <math>\log n!</math>.

Also, on Wikipedia, words don't customarily get capitalized just because they're in section headings.
