Generic word for firearms with long barrels. And since you have $\iff$ ‘if and only if’ at each step, this argument shows that the elements of $(A\cap B)^c$ are exactly the same as those of $A^c\cup B^c$ and hence that $(A\cap B)^c=A^c\cup B^c$: you’re done at that point.

(By the way, I think that you actually had a decent general idea of what was going on, but you need to be more careful about exactly what kinds of objects you’re dealing with; it’s a good idea, especially when you’re just starting, always to ask yourself whether statements, especially statements with a lot of technical notation or terminology, actually make sense.
