For sets A and B, determine whether A = B, A is a subset of B, or B is a subset of A
A = { x| x є N and 13 < x < 18} = [14,15,16,17}
B = { 12, 13, 14, 15, 16, 17, 18}
----------------
A is a subset of B

The description of A tells us that the elements in A must be positive integers (or perhaps non-negative integers depending on who is defining the Natural numbers) and that all elements of A are greater than 13 and all elements of A are less than 18. So you could enumerate set A rather easily by:



Now you can see that there are elements in B not contained in A, so:



B Ë A

but all of the elements of A are also contained in B, so:
