But above source make an error like bellow
Reading file "g:\Haskell\OperationTest.hs":

ERROR "g:\Haskell\OperationTest.hs":8 - Ambiguous variable occurrence "+"
*** Could refer to: OperationTest.+ Prelude.+
There's already a definition for (+) imported from the Prelude. When you 
write "Succ (m + n)" the interpreter doesn't know whether you mean the 
one you've just defined ("OperationTest.+") or the one imported from the 
Prelude ("Prelude.+").
