• 

This function corresponds to the sum of f for i in the given range.  It is an unevaluated form of the Maple sum function, so only some minor simplifications are performed. Expressions involving Sum can be manipulated by routines such as expand, and changevar.

• 

Use value to force Sum to evaluate like sum.

The command with(student,Sum) allows the use of the abbreviated form of this command.
