The instructions for "6. More than one argument" are to "Define a function called `add_function`

that has 2 parameters `x`

and `y`

and adds them together."

That would be this:

```
m = 5
n = 13
# Add add_function here!
def add_function(x, y):
x + y
print add_function(m, n)
```

That's an odd set of instructions, because nothing is done with the summed value of `x`

and `y`

. Additionally, this solution is not counted as correct, because the function is supposed to *return* the sum of `x`

and `y`

. I think the exercise would be clearer if this extra step were mentioned in the instructions.

How about this?

"Define a function called `add_function`

that has 2 parameters `x`

and `y`

, adds them together, and returns the total."
