Bummer: Uh oh, I didn't get the correct value returned. It should have been 50. Instead, it was None
What did i miss? What’s wrong with my code?
# enter your code below def mathy(a, b, c): if a == 'add': return b+c elif a == 'substract': return b-c elif a == 'multiply': return b*c elif a == 'divide': return b/c else: return None
In the line
elif a == 'substract':, you misspelled subtract. Other than that, your code looks fine.

Try passing in some value on a function call.
It looks to me like you've got your function but it needs to do something with some values and you get those values when you call the function.
So the first parameter
a, is where you get the string and how the program decides what kind of calculation to make.
mathy('divide', 15, 5)
