Quantifiers - does this order matter?

  1. Jun 17, 2011 #1
    Is saying [itex]\exists[/itex]x, [itex]\exists[/itex]y
    the same as saying [itex]\exists[/itex]y, [itex]\exists[/itex]x?

    Hi gmmstr827! :smile:

    No, in this case, the order doesn't matter.

    Alright, because the professor I have right now thinks those are two completely different things. He reads it as "there exists an x such that there exists a y (for that specific x)." This is the second time I had the class (it didn't transfer colleges) and my previous professor said they're the same thing.

    Is there a law describing this somewhere?
