Question

What are some examples of summation notation?

Answer 1

`sum_(n=1)^ooa_n=a_1+a_2+a_3+...`

`sum_(n=0)^10n^2`

Explanation:

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`
