Mathematical notation issues
Hello. Please notice this difference:
 * n*(n-1)
 * n(n &minus; 1)

In non-TeX mathematical notation, variables should be italicized by digits and punctuation should not. A minus sign rather than a stubby littly hyphen should be used and should be preceded and followed by a space (and similarly with "+", "=", etc. See Manual of Style (mathematics).  I usually make the spaces non-breakable with binary operators like "+", "&times;", etc.

I regard the use of an asterisk for ordinary multiplication as something to be done only when the available character set is severely limited, as on an old-fashioned typewriter. You can write:
 * nm
 * n&middot;m or n &middot; m
 * n&times;m (not to be confused with nxm) or n &times; m
