So "subscription" means "intersect". But:

Does "charactrist" mean "characteristic"? Does "Ú" mean "U" (or "union")?

What have you tried? How far have you gotten? Where are you stuck? Please be complete. Thank you!

"Ú" mean "U" (or "union")

sorry ,my bad.

Like they told you at the other site, both of these are wrong. YOu can't prove them.Proof without use of charactrist function that:

a) A Subscription B is the largest set containing both A and B

b) A Ú B is the smallest set containing both A and B

"subscription" means "intersect"

"charactrist" mean "characteristic"

"Ú" mean "U" (or "union")
