Like integral, sum expression can be added using the \sum_{lower}^{upper} command. In similar way you can obtain expression with product of a sequence of factors using the \prod_{lower}^{upper} command. Limit expression can be added using the \lim_{lower} command. Here is an example LaTeX document: Integral \(\int_{a}^{b} x^2 dx\) inside text.
4 Ιαν 2013 · To add multiple things under a math operator (like \sum), see How do you put multiple things under a limit?, which suggests \substack (as I've done in the last horrible visual).
In order for some operators, such as \lim or \sum to be displayed correctly inside some math environments (read $......$), it might be convenient to write the \displaystyle class inside the environment. Doing so might cause the line to be taller, but will cause exponents and indices to be displayed correctly for some math operators.

I want to write expression \sum_{i=0}^n i with i\neq 4 under the summation symbol. How can I write this? You can use \substack: If this is desired in inline math you can use \limits to obtain the limits underneath the summation symbol:
The following example takes this a step further. \newcommand{\mbr}[1]{\mathbb{#1}} Here, [1] is an argument that we send to the command \mbr and in turn we get the output \mathbb{1}.
This is a concise summary of recommended features in LATEX and a couple of extension packages for writing math formulas. Readers needing greater depth of detail are referred to the sources listed in the bibliography, especially [Lam], [AMUG], and [LFG].
