Given that π is equal to this set, with elements π, β, and π and π is a set with elements β, π, π, and π, find π minus π.

So we want to take the elements of π and subtract the elements of π. So we want to subtract the yellow ones from the blue ones. So first, we can subtract an β. So we subtracted an β from the set π. Now, the set π has an π. However, the set π doesnβt have an π. So we canβt really subtract it. And then we have an π which we also canβt subtract. However, there is a π.

So if we take away that π, what do we have left with π? Because weβre taking this set π and then taking away the elements from π. So once we take away those elements from π, what is left in π is simply element π. So this will be our final answer.
