6 Νοε 2023 · In this article, we shall explore the various commands to typeset summations with numerous examples. In mathematics, summation is denoted by the Greek capital letter sigma (∑). The command for displaying a summation sign is \sum and \Sigma. Although \Sigma and \sum return the same type of symbol.
Sum $\sum_{n=1}^{\infty} 2^{-n} = 1$ inside text \[ \sum_{n=1}^{\infty} 2^{-n} = 1 \] In similar way you can obtain expression with product of a sequence of factors using the \prod_{lower}^{upper} command.
In LaTeX, if you just want to subtract one known length (say, 1cm) from another (say, \textwidth) to obtain a new length variable, you can do so using the \newlength, \setlength, and \addtolength instructions, as in the following example:
It is very easy to produce the summation symbol (capital sigma) inside LaTeX’s math mode using the command \sum. The limits of the sum are then written using the common symbols for subscripts _ and superscripts ^ ( check this post ).
