Construct the negation of each statement below without using the following symbols: ∩, ∪, ⊆, ⊇, ⊂, ⊃, \, △, and =.
I know that the negation is simply $x∉A\cup B$, but how do I represent that without using the ∉ symbol? Thanks!
Could I say x ∈ ~A $\land$ ~B ?
Can I even use the and symbol $\land$ on sets?
