Answer 1

Something about proving equality between sets... appeals to me :D
You have to prove that they are subsets of each other... savvy? XD

Answer 2

hey, @msingh you with me?

Answer 3

yes

Answer 4

i was thinking how i can prove these subset of each other

Answer 5

Apparently, we're not allowed to use the method I mentioned... so use this...
\[\huge A\backslash B = A\cap B'\]

Answer 6

okay

Answer 7

So... we need to prove this, right?
\[\Large A=(A\backslash B) \cup (A\cap B)\]

Answer 8

(A∩B) this means A-B

Answer 9

Well, okay... we need to prove this
\[\Large A= (A-B)\cup(A\cap B)\] right?
