Want to verify let set $\left | A \right |=n$ and $\left | B \right |=m$ Then $max(m,n)\leq \left | A\cup B \right |\leq (m+n)$ $0\leq \left | A\cap B \right |\leq min(m,n)$ $0\leq \left | A- B \right |\leq \left | n \right |$ ... $\bigoplus$ is symmetric difference $0\leq \left | \overline{A} \right |\leq U$ here $\overline{A}$ is compliment of A and U is universal Set
