Answer1:Save the variable as global is one way.

```
def some_function():
global var #This is a global variable
#Do things to variable
```

The other way, which is what I believe you are looking for is to call a function inside of a function. This would look like this:

```
def function_1(#some variable):
#Stuff could be up here
num = function2(5)
#Stuff could be down here
def function_2(a_number):
a_number = a_number*2
return a_number
```

This will make the variable `num`

= 5*2.

I hope this helps.

Answer2:Functions can return values. You can store those values as variables. Then you can use those values as input to other functions.

I imagine you're trying to calculate the `OPS_value`

using `on_base`

and `slugging`

percentages.

So you would calculate `on_base`

, `total_bases`

, and `slugging`

and store the returned values in variables.

You then pass in those variables as input to your `OPS_value`

function, which returns the final, calculated value.

<strong>See the below example:</strong>

```
def OPS_value(percent):
"""(float) -> string
Return the on-base plus slugging value given the on-base plus slugging score range
>>>OPS_value(0.8234)
B
"""
if percent > 0.9000:
return "A"
elif percent > 0.7667:
return "B"
elif percent > 0.7000:
return "C"
else:
return "F"
total_bases = total_bases(2, 3, 4, 5) # Get the return value for total_bases
slugging = slugging_percentage(total_bases, 9) # Get the return value for slugging_percent
on_base = on_base_percentage(1, 2, 3, 4, 5)
print OPS_value(on_base + slugging) # using on_base + slugging as input
```

What we're trying to do is keep the math related to calculating each thing `total_bases`

, `slugging`

, etc separate.

The other major change from your original code is that you don't need to have a function for just adding two values. <strong>You can and should do that in one line.</strong>
