Hi please could anyone help me with this homework question?

i...Determine the elements of the sets
A={x | x\varepsilon N, 2 < x ≤ 5}

B={n | nN, n=x+3, x \varepsilon A}

ii...Given that n(AxB) = n(A) x n(B) what is the value of n(AxB) .

Thanks

I know that .
But I have no idea what means.
In particular: the part.
Can you clear up the notation?

Hi sorry my mistake

B={n | n\varepsilon N, n=x+3, x \varepsilon A}

Why not learn to post in symbols? You can use LaTeX tags
[tex]B=\{n: n\in N,~n=x+3,~x\in A\}[/tex] gives .

Just add 3 to each term if

Ok thank you for your help
