hi...i have a question....

if R is a set of real numbers, and Q is a set of Rational numbers, then R-Q=?

I think some of you misread the original setup. It said R is a set of real numbers and Q is a set of rational numbers. It didn´t say R was THE set of real numbers and Q was THE set of rational numbes. So R\Q (written as R-Q here) can of course contain rational numbers, e.g in the case R = {1,2} , Q = {1} => R\Q = {2}.
