sum (summation)

General syntax for symbols with a kind of lower and upper limits:

\symbolname_{<em>lowerexpression</em>}^{<em>upperexpression</em>}

In general, there are two ways how these lower and upper expressions can be placed: centered below and above the symbol or in a subscript / superscript manner. In the first case the symbol name is preceded by the word "big", in the second there is no prefix.
Syntax for summation symbol:

$$$\bigsum_{i=k}^{n}$$$ gives

$$\bigsum_{i=k}^{n}$$

and

$$$\sum_{i=k}^{n}$$$ gives

$$\sum_{i=k}^{n}$$

Use font size commands for a nicer picture:

$$$\LARGE\bigsum_{\small{i=1}}^{\small{n}}$$$ gives

$$\LARGE\bigsum_{\small{i=1}}^{\small{n}}$$

and

$$$\large\sum_{\small{i=1}}^{\small{n}}$$$ gives

$$\large\sum_{\small{i=1}}^{\small{n}}$$

Keyword(s):

$$$x^2$$$ or $$$x^3$$$ is $$x^2$$ or $$x^3$$
