hi,
if A = {1, 2, 4, 6} and B = {0, 2, 3, 4, 5}
my understanding is that 1 is not a subset of A and 0 is not a subset of B. however 1 is an element of A and 0 is an element of B.
---
also if A = { {1}, 2, {4}, 6} and B = { {0}, 2, {3}, 4, 5}
then i can say that 1 is a subset of A and 0 is a subset of B?
---
if A = { {1}, 2, {4}, 6} and B = { {0}, 2, {3}, 4, 5}
i can say that 4 is a proper subset of A and that 3 is a proper subset of B?
---
i thought i knew this stuff until i got my first quiz back...not good.
thanks.
