empty set is subset of any set integers contain all positive and negative integers including 0 so 0 does belong in them R is much bigger than N, in fact R is uncountable and N is countable, so R can't be a subset of N Integers contain positive integers which are essentially the natural numbers, so N is a subset of I also {1,2,...} is a subset of N since its N itself 4 doesnt belong in N since N doesnt contain any negative numbers

I was confused about what the different signs meant, but I'm more familiar with them now. Thanks for both of your time. :)

so if it asks Find A U B if A = {3, 6, 9, 12} and B = {2, 4, 6, 8, 10}. It would be {6} because U = the set of things that are in at least one member of A. Right?

A U B from A = {3, 6, 9, 12} and B = {2, 4, 6, 8, 10} would be {2, 3, 4, 6, 9, 12} and A n B from A = {3, 6, 9, 12} and B = {2, 4, 6, 8, 10} would be {6} Thanks for you links. :)
