# sum() function

The sum() function returns the sum of
a list of numbers delimited by attribute, value, or subvalue marks.
If different orders of marks are present, the sum() function computes the sum of each sublist.

## Syntax

```
sum(str.exp)
```

## Parameter(s)

| str.exp | List of numbers, delimited by attribute, value, or subvalue marks, from which the sum is calculated. |
| --- | --- |

## Description

The sum() function supports string math.

## Example(s)

The result, `6.2`, displays on the terminal.

```
crt sum(3:@am:3.2)
```
The result, `6.2^8`, prints because sum recognizes that there were two lists present, separated
by an attribute mark.

```
print sum(3:@vm:3.2:@am:6:@vm:2)
```
