Different
Two quantities are said to be different (or ``unequal'') if they are not Equal.
The term ``different'' also has a technical usage related to Modules. Let a Module 
in an Integral Domain 
for 
be expressed using a two-element basis as
where
and 
are in . Then the different of the Module is defined as
The different
Iff and are linearly independent. The Discriminant is defined as the square of the different.See also Discriminant (Module), Equal, Module
