# Arithmetic Assignment Operators #

You may have noticed that sometimes you need to write an assignment statement that uses the current value of the variable being assigned to. For example:

```
x = x + 1
```

You can write this a bit more concisely, as `x += 1`

. You can actually do this
with any arithmetic operator on a numeric variable:

```
x = 10
x += 5 # x is 15
x //= 3 # x is 5
x **= 2 # x is 25
```

The `+=`

operator also work with strings:

```
s = "sp"
s += "am" # s is "spam"
```
