#### Simpsum

-- Option variable: simpsum Default value: `false`

When `simpsum` is `true`, the result of a `sum` is simplified. This simplification may sometimes be able to produce a closed form. If `simpsum` is `false` or if the quoted form sum is used, the value is a sum noun form which is a representation of the sigma notation used in mathematics.

```(%o1)                                true
(%i2) ```
