I have a result from the command Reduce that looks like this (as an example): a:= x==3||x==4||x==7 I need to extract the numbers but I can't find a nice way to handle the case when there is only one equation, for instance: a:= x==6 currently I check what the head of the expression is (Head[a]) and handle the case Head[a]=Or with a Map[] and the case Head[a]="Equal" with a[[2]]. Not very nice, but I guess that there is a neat way to do it. cheers, Robert
