How do you write summation notation in Word?
The symbol’s code: You can insert symbols by typing the symbol’s code and then pressing the Alt+X key combination. For example, the code for the sigma character is 2211: Type 2211 in your document and then press Alt+X. The number 2211 is magically transformed into the sigma character.
How do I use summation notation?
The summation notation is mostly used to represents series or to express a series in a short form. For example : if I want to write the series : #1+4+9+16+25#. in summation notation I would simply write: #sum_(n=1)^5n^2#. See all questions in Summation Notation.
