     How do I tell Mathematica to regard a variable,n for example, as an

     integer.  Hence, things like Sin(n Pi) = 0.   I read 'n' books,
pardon 
     the pun, and still couldnt glean out the answer. In frustration I
just 
     gave up.  Thank God for Mathgroup!
     
     Also why is Simplify not built into operations automatically?  Some

     problems I double check by looking for zero as the solution but
dont 
     get that value until I add Simplify to the operation.
