# and & are parts of a Pure Function

/@ is a shortcut for the Map function

I suggest you use the Help to read about Pure Functions (It is a rather 
large and sometimes confusing topic for the beginner. Also very 
powerful.) And look up Map in the Help and check out the examples.

This is probably less than you wanted, but your question is more than 
you probably realize.
