## X:X?

Hi there,

I have never really done sets before and I am trying to understand the notations etc. Any how would I be correct in assuming that where it says x:x is exactly divisible by 3 and x:x is exactly divisible by 7 that it means that its a set that consists of all the numbers in set A that are divisible by 3 , and by 7?
