Bummer: Uh oh, I didn't get the correct value returned. It should have been 50. Instead, it was 150

Your function will need to complete the math operation and return the result. example: mathy('divide', 15, 5) return 3

mathy.py 
# enter your code below
def mathy(a, b, c):
    add = b + c
    return add

Hey Noor Hafiza Binti Ibrahim, the first parameter receives a string argument that is the name of a math operator. The function returns the result of this operator used between b and c.

An if/elif/else statement works well here to match the operator string. The body of each code block could simply be returning the result of the math operation being applied. For example 

if a == “divide”:
    return b / c
elif ....
```Python 

Post back if you need more help. Good luck!!!
