2=The difference of two Irrational number is either rational or an Irrational {Example:- (a) √2-√2=0

(b)=√2-√3=√2-√3}.

3=The product of rational and an irrational number is is always an irrational {Example :-2×√3=2√3}.

4=The product of two irrational number is either rational or irrational{Example :-(a) √2×√2=2.

(b)=√2×√3=√6}
