PrinceofLight2000 Posted August 30, 2011 Report Share Posted August 30, 2011 Question - "How do I do x?" Answer - "y" Question - "How do I do y?" Answer - "z" y =/= zIs this valid? Quote Link to comment Share on other sites More sharing options...
FunkyTown Posted August 30, 2011 Report Share Posted August 30, 2011 Is this valid?Yep. Y is not necessarily equal to Z in this case.It could be, but it's not necessarily."How do I fix my door so it doesn't squeak?""Get some grease and oil the hinges.""How do I get some grease and oil the hinges?""Go to the hardware store."It could be equal to Z, if the person in question explained the entire thing en toto, but obviously 'Go to the hardware store.' is not the answer to 'How do I fix my door so it doesn't squeak?'

MarginOfError Posted August 30, 2011 Report Share Posted August 30, 2011 You could write the statement x => y AND y => z. Notice that the statements are implications, not equivalencies. Quote Link to comment Share on other sites More sharing options...
