This expression is internal to the negotiator, so it is not visible as 
part of the machine ClassAd.  The best way I can think of to check the 
expression would be to evaluate it in a condor_status query.  Example:

condor_status -f "%g\n" '-Memory'

No, because $(...) is a macro substitution operator, so $(Memory) says 
to insert the value of a configuration macro named Memory when the 
negotiator is reading the configuration file.  Instead, you want to 
refer to the Memory attribute of the machine ClassAd (equivalently 
TARGET.Memory).
