You didn't import it all, you must do:

```
from math import *
sqrt(...)
```

otherwise, it is bound to math, like: `math.sqrt(...)`

you have to use `math.sqrt()`

@FineMouche you can set a variable like this:

`sqrt = math.sqrt`

Import

`sqrt()`

from math, like this:and then you can

Or else you have to do:

Or if you really want to you can do this

And if you want everything from math, just put * which imports everything.
