I am trying to write a basic algorithm for addition and it is giving me an error that says:
Traceback (most recent call last):
 Traceback (most recent call last):
 File "solution.py", line 6, in 
 print C
NameError: name 'C' is not definede
I erased the first print statement and it fixed this issue but now it says 'a'is not defined

```
def solveMeFirst(a,b):

    a = int(raw_input('A='))
    b = int(raw_input('B='))
    C = a+b
    print C
res = solveMeFirst(num1,num2)
print res

```
