The question is " Convert the arguments into floats by using the function ' float()' and then add the two arguments and return the total " Please help me to edit this code!

trial.py
```def add(a, b):
float(a)
float(b)
c= a + b
return c
``` That's because while `float(a)` returns the float version of `a`, it doesn't assign the new value for the name `a`. So when you run

```c = a + b
```

a and b are referring to the same thing as before.

To convert a to float and use it later for c, you have to tell python which name to point to the new value. So for instance to use the float version of a to calculate the sum you will need to do something like

```a_float = float(a)
```

You can also do more directly

```c = float(a) + float(b)
```

and then return c. Or even more straight-forward, just return the value without bothering with assigning new names:

```return float(a) + float(b)
```

Thank you so much!!!! ;)
