comment How to find all the pairs satisfying a relation?
No, there can not be a 'x' whose pair does not satisfy this relation. But still the problem remains about how do I find its domain and range?

comment How to represent the Cartesian product of an infinite set?
Thanks. Can you please help me out with the notations you used? In {a,b:a is a real number and n is 1,2, or 3} what is 'n' and why is there a need to define it?Moreover how would the person know that 'b' is also a real number?

comment How to represent the Cartesian product of an infinite set?
@Qiaochu and lhf: What I mean is that there are infinite terms in a set of all real numbers.Moreover as it includes all the floating point values so it more difficult to represent all of the elements of that set.

comment What does {2x|P(x)} mean?
Should I think that first I have to check the conditions of the preposition and then mark them true for all multiples of 2?

comment What is a null set?
Thanks. Very nicely explained. It means that I can also make up my empty sets myself excluding those examples like {x:x=4 and x is a prime} like this?
