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

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.
e.g.
mathy('divide', 15, 5)

Now i got: Bummer: Uh oh, I didn't get the correct value returned. It should have been 59. Instead, it was 0.84375
