# + arithmetic operator

The + arithmetic operator performs addition
or indicates a positive numeric value.

## Syntax

```
num.exp + num.exp
```

## Example(s)

Adds `1` to the
variable, `x`.

```
x = x + 1
```
Adds the values in the variables `price` and `tax` and assigns the result to `subtotal`.

```
subtotal = price + tax
```
This is a complex arithmetic statement that first multiplies
the `unit.cost` by `qty` and then adds
the results to the variable called `tax`. The left
and right parentheses are used to explicitly group precedence.

```
subtotal = tax + (unit.cost * qty)
```
