I need help rewriting the following equation using just the or operator and the not. My teacher did this in class in a hurry and then erased it. I was trying to do this but I misunderstood what he was asking so I redid it I'm just not sure if what I did is correct. Heres the equation.

$[( p \Rightarrow q ) \wedge ( r \Rightarrow s)] \Rightarrow [(p \vee r ) \Rightarrow (q \vee s )]$

1. This is not an equation, it's an expression

2. $p\Rightarrow q = p\lor\lnot q$

3. $\lnot p\land\lnot q = p\lor q$
